Question

A bucket made of metal sheet is in the form of a cone whose height is 35 cm

Answer 1

Answer:

51.48 litres

Step-by-step explanation:

∵ The bucket has two circular ends with different radii, it is a frustum of cone

Capacity of Bucket = Volume of Frustum of cone

\frac{1}{3}\times \pi \times height ( Radius_1^2 + Radius_2^2 + Radius_1 \times Redius_2)

\frac{1}{3}\times \frac{22}{7} \times 35 ( 30^2 + 12^2 + 30 \times 12)

= (110/3) × (1404)

= 51840 cm³

∵ 1 cm³ = 1/1000 Litres

∴ Capacity of bucket in litres = 51840 × (1/1000) = 51.48 litres

∴ Bucket can contains 51.48 litres milk in it.
