A water tank is in the shape if a right circular cylinder with a height if 20 feet and a volume if 320 (pie) cubic feet.
What is the diameter, in feet of the tank?
:
The volume of a cylinder: V =
This problem
=
divide both sides by pi
20r^2 = 320
r^2 =
r^2 = 16
r =
r = 4, the diameter is 8 ft obviously
