Question

A
solid sphere is melted to get 6 cylinders of diameter of
4cm
and height 12 cm. Find the radius of the sphere.​

Answer 1

Answer:

3 cm

Explanation:

ATQ,

Volume of sphere = Volume of cylinder

4/3π r^3 = π r^2h

4/3 r^3 = 4 * 12. ( π gets cancelled)

r^3 = 36 * 3/4

r^3 = 27

r = 3

The radius of sphere is 3 cm
