Question

A heap of rice is in the form of a cone of diameter 12 m. and height 8 m. Find its volume? How much canvas cloth is required to cover the heap?
(use π = 3.14)

Answer 1

Answer:

188.5 cm²

Step-by-step explanation:

Given,Diameter = 12 m.

Radius = 6 m.

Height = 8 m.

Volume of rice in the heap = (1/3) πr²h

= (1/3) * (22/7) * (6)² * 8

= 301.71 m³.

Now,

l = √r² + h²

 = √6² + 8²

 = 10 m

∴ Canvas cloth required to cover the heap = πrl

= (22/7) * 6 * 10

= 188.57 cm²

Hope it helps
