Question

If the radii of the circular ends of a bucket of height 40cm,28cm and 7cm respectively.Find the volume of the bucket

Answer 1

Answer :

The bucket is in the shape of a frustum,

Volume of bucket=volume of frustum

=1/3πh(R^2+r^22+Rr)

=1/3*3.14*40(28*28+7*7+7*28)

=125.6/3(784+49+196)

=125.6/3*1029

=125.6*343

=43080.8 cm^3
