Question

4. If the volume of a right circular cone of height 9 cm is 48 cm, find the diameter of its base.​

Answer 1

Step-by-step explanation:

Height of a cone = 9 cm

Volume of cone = 48 π cm3

We know, Volume of cone = 1 3 13πr2h

48π = 1 3 13π r2 x 9

r2 = 16

or r = 4

Radius of base r = 4 cm

Therefore, Diameter = 2 Radius = 2 x 4 cm = 8 cm.
