Question

A metal sphere of radius is 5cm is melted to make a cone with Base of the same radius . What is the high of the cone.

Answer 1

let, radius of sphere =r=5cm

volume=v1

v1=4/3*22/7*5*5*5

radius of cone is same

volume of cone be v2

height be h

v2=v1

1/3*22/7*5*5*h=4/3*22/7*5*5*5

h=20cm
