Volume of hollow cylinder

What is the volume of a hollow cylinder with R, r and h as outer radius, inner radius and height respectively?

What is the volume of a hollow cylinder open at both ends, if its length is 25 cm, external radius is 10 cm and thickness is 1 cm ? (Take pi = (22)/(7) )

Volume of a hollow Cylinder

Ampere Circuital Law , field due to hollow cylinder , field due to solid cylinder

If the external radius of a hollow cylinder be R units, the internal radius be r units and the height be h units, then the volume of the cylinder is

The difference between the outer and the inner curved surface areas of a hollow cylinder, 14cm long, is 88sq. cm. Find the outer and the inner radii of the cylinder, given that the volume of metal used is 176cu.cm.

Find the ratio of radii of gyration of a hollow cylinder and a solid cylinder about an axis passing through their centres and parallel to length.

True/false In case of a hollwo cylinder. Inner curved surface area of a hollow cylinder= 2pih(R-r)
