Greg�s company manufactures a cylindrical can with a diameter of 8 inches and a volume of 245 cubic inches.

a. Find the height of the original can to the nearest in.
V = pi*r^2*h
--
245 = pi*4^2*h
---
height = 245/(16pi) = 4.87 inches
-----------------------------
b. If the diameter stays the same and the height is doubled, find the new volume of the new can to the nearest cubic inch.
V = pi*4^2*(2h)
V = [pi*16*2h]
V = 2[pi*16*h]
V = 2*245
V = 490 cu in
