What is total surface area of cylinder?The surface area of a cylinder refers to the total area that the cylinder's curved surface and circular bases cover. The total surface area of the cylinder includes the area of the 2 bases of the cylinder (each of which is in the shape of a circle) and the area of the curved surface.
Given that, the radius of a cylinder is 6 units and the height of a cylinder is 15 units.
We know that, the total surface area of a cylinder is 2πr(r + h).
Now, the surface area = 2×π×6(6+15)
= 2×π×6×21
= 252π square units
Therefore, option D is the correct answer.

PLEASE HELP 15 POINTS + BRAINLIEST Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. midpoint - (-15,22) endpoint- (-8,15) Please help oh and heres the hint included (Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.)
FIRST TO ANSWER CORECTLY IS BRAINLIEST
Answer:
end point ₂ of a segment X₂ = - 22 ; Y₂ = 29
Step-by-step explanation:
given;
midpoint = ( Mx = - 15 , My = 22 )
endpoint ₁ = ( X₁ = - 8 , Y₁ = 15 )
find the other endpoint ₂ ( X₂ , Y₂)
use the mid point formula to get the other endpoint:
Mx = ( X₁ + X₂ ) / 2 My = ( Y₁ + Y₂ ) / 2
- 15 = (-8 + X₂) / 2 22 = (15 + Y₂) / 2
-30 = - 8 + X₂ 44 = 15 + Y₂
X₂ = -22 Y₂ = 29
Answer:
So, the formula for finding the midpoint of a segment given the coordinates of its endpoints is: ((x 1 + x2)/2, (y 1 + y 2 )/2 {Average of the x coordinates, average of the y coordinates}. For this problem we know the coordinates of the midpoint along with one of the endpoints.
Step-by-step explanation:
Use the midpoint formula
M = ( (x1 + x2) / 2 , (y1 + y2) / 2 )
(9, 0) = ( (x1 + 12) / 2 , (y1 + 3) / 2)
Break up this formula into two equations.
(x1 + 12) / 2 = 9 and (y1 + 3) / 2 = 0
Solve for x1 and y1 from the equations.

Which do you prefer: leaving √5 in radical form, or converting it to a decimal? Why? When would it be useful to use each?
Answer:
I prefer leaving the answer as √5 since it is a shorter form and exact form of the answer.
Here are reasons for leaving it as a radical form or a decimal approximation.
If you are looking for an exact answer, then you should leave it as √5. For example, if you are told a square has area 5 square units, then the exact length of the side is √5 units.
If √5 is the length of something that has to be made to that length, then you need an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then you need an approximation of √5 ft, such as 2.24 ft, so you can make each side of the cardboard square in the length of 2.24 ft.
We shall prefer to keep √5 in radical form, as it is an irrational number and will never give an exact value when converted to decimal form.
What are rational and irrational numbers?A rational number is any number that can be represented in the form p/q, where p and q are integers, q ≠ 0, and p, q are co-prime to each other, that is, they do not have any common factor except 1.
All terminating and non-terminating recurring decimals are rational numbers.
An irrational number is a real number that cannot be represented in the above form of a rational number.
All non-terminating non-recurring decimals are irrational numbers.
How do we solve the given question?We are asked, what would we prefer to do. Leave √5 in radical form or convert it into decimal form.
∵ √5 is an irrational number, we will never get a perfect value of it in decimal form, as irrational numbers are non-terminating non-recurring decimals. So, we shall prefer to keep √5 in the radical form.
Use of √5 in radical form: Gives the exact value in our calculations for equations.
Use of √5 = 2.236067977499........... in the decimal form: Used in trigonometry where we need to find the trigonometric ratio.

Solve the system: 4x - y = 5 x + 2y = 8
Answer:
x = 2y = 3Step-by-step explanation:
4x - y = 5..........… Equation 1
x + 2y = 8 ............. Equation 2
Make x the subject in equation 2 and substitute it into equation 1
That's
x = 8 - 2y
We have
4( 8 - 2y ) - y = 5
32 - 8y - y = 5
- 9y = - 27
Divide both sides by - 9
We have the final answer as
y = 3Substitute y = 3 into x = 8 - 2y

You have 2 positive numbers. One number is one-fifth of the other number. The difference between the two numbers is 228, find the numbers.
Hey there! I'm happy to help!
Let's call these numbers x and y and model the information we have.
x=1/5y
y-x=228 (we see that x is smaller than y in the first equation, so we put it second )
We see that x is equal to 1/5y. We can switch the x in the second equation with 1/5y and solve for y.
y-1/5y=228
4/5y=228
We divide both sides by 4/5.
y=285
We know that x is 1/5 of y, so we divide by 5.
285/5=57
x=57
So, our numbers are 57 and 285.
Have a wonderful day! :D
The 2 positive numbers are 285 and 57 and they have a difference of 228.
EquationAn equation is an expression used to show the relationship between two or more numbers and variables.

I NEED THIS ANSWER TODAY PLEASE!!!! A hotel manager found that his gross receipts for the day, including a 3% sales tax, were $2766.58. Find the amount of sales tax collected.
==================================================
Work Shown:
x = amount of money collected before tax is added
3% = 3/100 = 0.03
3% of x = 0.03x = amount of tax
x + 0.03x = adding on tax to original amount
1.03x = amount after tax is added
1.03x = 2766.58
x = 2766.58/1.03
x = 2686 is the amount of money before the 3% sales tax is added
0.03x = 0.03*2686 = 80.58 is the amount of sales tax collected
As a check,
2686+80.58 = 2766.58
which confirms our answer
Answer:
Tax collected= $80.58
Step-by-step explanation:
Let's say that the amount he got from services was "x", and to that he had to add a 3% of sales tax.
Recall that 3% in math form is written as: 3/100 = 0.03
then, he had to include 0.03 times x to the "x" amount in hotel services:
x + 0.03 x = 2766.58
1.03 x = 27688.58
x = 27688.58/1.03
x= $2686
Then, the amount for the taxes is 3% of this which is:
0.03 * 2686 = $80.58
NEED ANSWER ASAP!!!!! Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. The circle has a diameter of 6 inches.
====================================================
Explanation:
See the diagram below. We're looking for the area of the shaded region in blue.
This is known as an inscribed circle since the circle is inside the square, touching each side at one point. This circle is as large as possible without spilling outside the square. Think of a balloon that has been inflated as much as possible to fill the room (it touches every wall at a tangent point).
The square has area s^2 = 6^2 = 6*6 = 36 square inches.
The circle has area pi*r^2 = pi*3^2 = 9pi square inches exactly. Note how I cut the diameter (6) in half to get the radius (3).
The blue shaded area is the difference of the square and circle areas, so we have 36 - 9pi as the exact area of the shaded region.
Using your calculator, you should find that 36-9pi = 7.72566611769187 approximately. I'm using my calculator's stored version of pi as opposed to something like pi = 3.14; but you may need to ask your teacher for clarification about what version of pi to use.
When rounding to the nearest tenth, we then get roughly 7.7 square inches as our final answer.

Answer:
Francis Drake was born in the UK and he's a naval officer
Step-by-step explanation:
Drake is most famously known for his circumnavigation of the world in a single expedition, from 1577 to 1580, and was the first to complete the voyage as captain while leading the expedition throughout the entire circumnavigation. He discovered that Tierra del Fuego, the land south of the Magellan Strait, was not another continent as Europeans believed, but instead a group of islands. This meant that ships could sail between the Atlantic and Pacific oceans around the bottom of South America (later known as the Cape Horn route).
