If the radius of right circular cylinder is tripled and the height gets halved, then the ratio of new volume to the previous volume of the cylinder is1 : 31 : 24 : 39 : 2

The volume of a cylinder is 300π m3.If the height of the cylinder is doubled and the radius is halved, the new volume will be:150π m3300π m3450π m3600π m3

A right cylinder and a right circular cone have the same radius and the same volume. The ratio of the height of the cylinder to that of the cone is:3 : 52 : 53 : 11 : 3

If the ratio of the radii of two cylinders is 2:12:1 and the ratio of their heights is 1:21:2, find the ratio of their volumes.1:21:22:12:11:11:11:41:4

The radius of a right circular cylinder increases at the rate of 0.2 cm/sec and the height decreases at the rate of 0.1 cm/sec. The rate of change of the volume of the cylinder when the radius is 1cm and the height is 2cm is

The base radius of cylinder  is twice the base radius of cylinder , and the height of cylinder  is twice the height of cylinder . What is the ratio of the volume of cylinder  to the volume of cylinder ?
