ConceptSurface Area of a Right Circular Cone

#### Question

A heap of wheat is in the form of a cone of diameter 9 m and height 3.5 m. Find its volume. How much canvas cloth is required to just cover the heap? (Use 𝜋 = 3.14).

#### Solution

Given diameter of cone 14cm

Height of cone =51cm

∴ Volume of cone=1/3xxpir^2h

=1/3xx22/7xx7xx5xx51

= 2618 cm^3

It is given that 1cm^3 weight 10gm

∴ 2618cm^3 weight (261xx10) gm

i.e, 26.180kg.
