Question
A water tank is in the shape of a right circular cylinder with a height of 20 feet and a volume of 320pi cubic feet. What is the diameter, in feet, of the water tank?
Answers
V = π r^2 h
320π = π(r^2)(20)
r^2 = 320π/(20π) = 16
r = 4
so the diameter is 8
320π = π(r^2)(20)
r^2 = 320π/(20π) = 16
r = 4
so the diameter is 8
Thx helped me on test
