Question

The perimeters of the ends of a frustum of a right circular cone are 44 cm and 33 cm. If the height of the frustum be 16 cm, find its volume, the slant surface and the total surface.

Answer 1

Given perimeters of ends of frustum right circular cone are 44cm an 33cm

Height of frustum cone = 16cm

Perimeter = 2πr

Let slant height of frustum right circular cone be l

Slant height of frustum cone = 16.1cm

Curved surface area of frustum cone

Total surface area of frustum cone = 860.27cm²
