If the radius of the base of a cone is tripled and the height is doubled then the volume is

If the radius of the base of a cone is doubled and the height is tripled then the volume is:

The radius of the base of a cone is 21 cm and the height is 20 cm. Find the volume the cone

The radius of base of a cone is r and height is h. Find its volume.

The radius of base of a cone is r and height is h. Find its volume.

If the radius of the base of a cone be doubled and height is left unchanged, then ratio of the volume of new cone to that of the original cone will be :

Keeping the radius of a cone fixed, If the height is doubled, then the volume of the cone is increased by

If the radius of the base of a right circular cone by halved and its height be doubled , then the volume of the cone remains the same.

If the radius of the base of a cone is halved, keeping the height same, what is the ratio of the volume of the reduced cone to that of the original cone?

If the radius of the base of a cone is halved, keeping the height same, what is the ratio of the volume of the reduced cone to that of the original.

If the radius of the base of a cone is halved, keeping the height same, what is the ratio of the volume of the reduced cone to that of the original.
