A cylinder with a volume of 576pi m3 is circumscribed about a square prism which has one side of the base that measures 8m.
What is the altitude of the cylinder?
:
The diagonal of the square base of the prism is also the diameter of the base of the cylinder
d = sqrt%288%5E2%2B8%5E2%29
d = 11.314 m diameter
r = 11.314/2 = 5.657 is the radius
therefore
pi%2A5.657%5E2%2Ah+=+576%2Api
divide both sides by pi, square 5.657
32h = 576
h = 576/32
h = 18 m is the altitude of the cylinder
