Answer:
The radius is approximately 11 feet. More exactly 10.997 when rounded to the nearest thousandth.
Explanation:
A cylinder has a height of 20 feet.
h = 20
Its volume is 7,598.8 cubic feet.
V = 7598.8
The formula for the volume of a cylinder is:
V = pi•r^2•h
Fill in what is given.
7598.8 = pi•r^2•20
Now there is only one variable in the equation, r and we can solve for it.
Divide both sides by 20pi.
120.938658 = r^2
We will have to square root both sides to find r.
10.997 = r
So the radius is 10.997 feet (to the nearest thousandth) or round to 11 feet.
