Solution:
Note that:
Circumference = 50.24 ft = 2πr = πdDia. = 16 ft.Divide the diameter both sides.
50.24 ft = πd=> 50.24/d ft = πd/d=> 50.24/d ft = πSubstitute the diameter in the equation.
=> 50.24/16 = π (Option A)Related Questions

Answer:
f(x)=2x-11
f(6)=2(6)-11
=12-11
=1
and the answer is c.
Explanation:
f(6) means you have to replace all x's in the function with 6.
For example, if the problem was asking you what is the value of f(10) you would have to replace all the x's in the respective function with 10 and so on.
Because it is three-dimensional, a form has these three spatial measurements: height, width, and ________.
Answers
Considering that it is a three-dimensional form, it's spatial measurements are height, width and length.
What are the measurements of a three-dimensional form?A two-dimensional form has two dimensions, width and length. When there are three dimensions, the height is added.
In this case, height and width are already listed, hence the length is missing.

If you place a 32-foot ladder against the top of a 23-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Answers
Answer:
22.2 feet
Step-by-step explanation:
Treat the ladder, building, and the ground between the bottom of the ladder and the building as the legs of a right triangle.
Then, you can use the Pythagorean Theorem.
X^2 + Y^2 = Z^2
The ladder is the "diagonal" side, so it is the hypotenuse, Z.
It doesn't particularly matter whether the building is X or Y; the end result will be the same.
Therefore:
(23)^2 + Y^2 = (32)^2
Y^2 = (1024 - 529) = 495
Y = 22.249; rounded to the nearest tenth, 22.2 feet

42 + x = 2 (9 +x) (solve for x)
42 + x = 18 + 2x
42 -18 = 2x -x
24 = x
42 + 24 = 66
9 + 24 = 33
