A right triangle ABC with sides 5 cm, 12 cm and 13 cm is revolved about the side 12 cm.

Find the volume of the solid so obtained


When right-angled ΔABC is revolved about its side 12 cm then a cone is formed having

Height (h) = 12 cm


Radius (r) = 5 cm


Slant height (l) = 13 cm



Volume = r2h


= * * 5*5 * 12


= 100 cm3
