That will depend on its height which has not been given but the volume of a cylinder is pi*radius squared*height.

A cylinder with a radius of 7 cm and a height of 10 cm has a volume of 1539.38 cm3.

Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.

The volume of a cylinder, V, is given by the formula:V = pi*r^2*h where r is the radius and h is the height of the cylinder. It is necessary to know both the radius and the height before you can determine the volume.

The radius IS given, since height of hemisphere = radius of hemisphere!

You use algebra. You know that the volume of a cylinder is: Volume = (pi)(radius2)(height) If you divide each side by (pi) and (radius), you get: Volume/[(pi)(radius2)] = height

Volume of Cylinder = Pi x radius2 x height Therefore for a cylinder with a radius of 5 units and a height of 7 units is given by Volume = 3.14 x 52 x 7 = 549.5 (cubic units)

Volume of Cylinder = Pi x radius2 x height Therefore for a cylinder with a radius of 7 units and a height of 6 units is given by Volume = 3.14 x 72 x 6 = 923.16 (cubic units)

The answer depends on what information you are given: volume and height, or surface area and height, etc.

The radius of a cylinder given only the height could be anything you like.

The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
