Cone: slant height: volume: CSA: TSA

Frustum of a cone: formation and formulas ( slant height: volume: CSA: TSA)

In a hemisphere, r=7 cm then CSA = cm^(2).

A hemisphere is inscribed in a cylinder and a cone is inscribed in the hemisphere .The vertex of cone lies on the centre of the upper circular part of the cylinder .Show that , (1)/(3)xx Volume of cylinder = (1)/(2) xx Volume of hemishphere= Volume of cone
