Answer 2

Given:

Diameter = 24 m

Height = 3.5 m

To find:

Volume

Cloth required to cover  

Solution:

Volume = 1 / 3 * π * ( radius )^2 * height

Here,

Radius = diameter / 2

Radius = 12 m

Substituting,

1 / 3 * 3.14 * ( 12 )^2 * 3.5

Volume = 528 cu.m

The cloth required to cover = π * radius * length

To find length,

Length = √ ( height )^2 + ( radius )^2

Substituting,

√ ( 3.5 )^2 + ( 12 )^2

Hence,

Length = 12.5 m

3.14 * 12 * 12.5

The cloth required = 471.4 sq.m
