Choose the correct alternative answer for each of the following question.

A cone was melted and cast into a cylinder of the same radius as that of the base of the cone. If the height of the cylinder is 5 cm, find the height of the cone.
A. 15 cm

B. 10 cm

C. 18 cm

D. 5 cm

Answer :

Height of cylinder, H = 5 cm

Height of cone =h

Volume of cylinder, V = πr2H

Since cone is melted to form cylinder,

V = v

h = 3× H

h = 3 × 5

h = 15 cm

Option (A) is correct
