A cone with diameter of its base as 30 cm is formed by melting a spherical ball of diameter 10 cm. What is the approximate height of the cone?

1.2 cm

2.2 cm

3.2 cm

6.2 cm

Radius of cone = 30/2 = 15, radius of ball =
10/2 = 5
Volumes will be equal, so
(1/3) π r²
h = (4/3) π R³15²
h = 4* 53
So h = 2.2
