I need help doing part b and c.

b) calculate a possible radius and height of a cylinder that has the same volume as the cone.

c) If the radius of the cylinder is the same as the radius of the cone, what is the height of the cylinder?

**Steve**, Saturday, November 24, 2012 at 11:08amv = pi/3 r^2 h = pi/3 * 36 * 9 = 108pi

for cylinder,

v = pi r^2 h, so a cylinder 1/3 as high would have the same volume as the cone.

see above. same radius, 1/3 height.
