the 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
