Q:
# A water tank is in the shape of a right circular cylinder with a height of 20 feet and a volume of 320π cubic feet. What is the diameter, in feet, of the water tank?

Accepted Solution

A:

The formula for volume of a cylinder is V=π r^2 h.

So plug in,

320π=π r^2 20

solve (sadmep (opposite of pemdas))

divide pi out

320=r^2 20

divide 20 out

16=r^2

square root of 16 is 4, so the radius is 4.

Since the 2r=d, the diameter is 8.
