volume of a cone = 1/3* π* r^2* h
its given,
volume = 216π --------------1
radius= 9 -------------2
substitute 1 and 2 in the formula,we get
216π = 1/3 π * 9 * 9
π gets cancelled.
216 = 1/3 * 81 * h
h= 216 *3 * 1/81
h = 648 / 81
h= 8 cm//
height of the cone = 8cm

with formula of volume of a cone
=1/3π r^2 h
we are given ,
V = 216π
radius= 9
volume and radius in the formula ,
216π = 1/3 π * 9 * 9
216 = 1/3 * 81 * h
216 *3 * 1/81=h
648 / 81=h
8 cm = h
thus ,
height of the cone = 8cm
hope it helps!!!
