Cone: slant height: volume: CSA: TSA

Hemisphere: volume: CSA: TSA

Cylinder: volume: CSA: TSA

The radii of the ends of a frustum of a cone 40 cm high are 38 cm and 8 cm. The slant height of the frustum of cone is

Formula to find the slant height of a cone is

If the radii of circular ends of a frustum of a cone are 20 cm and 12 cm and its height is 6 cm, then the slant height of the frustum is ……. cm.

The radii of the circular ends of a frustum of a cone are 14 cm and 8 cm. If the height of the frustum is 8 cm, find (i) slant height of frustum (ii) total surface area of frustum (iii) Volume of frustum, (pi=3.14)

The height of a cone is 21 cm and its slant height is 28 cm. the volume of the cone is

The height of a cone is 21 cm and its slant height is 28 cm. The volume of the cone is

The radius of the base of a cone is 4 cm and slant height is 5cm. Its CSA is :
