The diameter of two circular ends of a bucket are 44 cm and 24 cm, and the height of the bucket is 35 cm. The capacity of the bucket is

Given: Diameter of two circular ends of a bucket are 44 cm and 24 cm, and the height of the bucket is 35 cm.


Bucket is in the shape of frustum.


Let V be the Volume of the Bucket(Frustum)


Volume of the frustum is given by: × h × (R2 + r2 + Rr) (here r and R are the radii of smaller and larger circular ends respectively)


V = × h × (R2 + r2 + R × r)


V = × 35 × (222 + 122 + 22 × 12) (diameters are 44 and 24 cm, their radii are 22cm and 12cm respectively)


V = × 35 × (484 + 144 + 264) = × 35 × (892)


V = × 35 × (892) = 32706.6 cm3 = 32.7 litres ( 1000cm3 = 1 litre)


The capacity of the bucket is: 32.7 litres
