**Reiny**, Friday, February 1, 2013 at 12:06amthe volume of a cone , regular or oblique,

= (1/3)πr^2 h

if h = 2r

V = (1/3) π r^2 (2r) = (2/3)π r^3

but (2/3)π r^3 = 18π , (I assumed your 3.14 was supposed to be π )

(2/3) r^3 = 18

2r^3 = 48

r^3 = 24

r = 24^(1/3) = appr 2.885 cm

or 3 cm to the nearest cm

neat little applet here for an oblique cone
