**Jai**, Monday, May 21, 2012 at 6:06amrecall that the volume of an oblique cone is given by

V = (1/3)*(πr^2)*h

where

r = radius of circle (the base)

h = height

since diameter is equal to the height, we can say that

h = d = 2r

substituting,

V = (1/3)π(r^2)(2r)

18π = (2/3)π(r^3)

18*(3/2) = r^3

27 = r^3

r = 3 cm

h = 6 cm

hope this helps~ :)
