A cylindrical glass is made up of steel whose internal radius is 7 cm and external radius is14 cm and and height is 10cm,then find its volume in cubic centimetre. (assuming the glass is uniform and the width of steel is same everywhere)

I think you want the volume contained between the 7 and 14 cm radii?

Volume of cylinder = pi r^2 h

Take the volume of the 14 cm cylinder then subtract the 7 cm cylinder

pi (14^2)*(10) - pi 7^2(10) = ........ cm ^{3}
