#### Question

The largest sphere is to be curved out of a right circular of radius 7cm and height 14cm. find volume of sphere?

#### Solution

Given radius of cylinder (r) = 7cm

Height of cylinder (h) = 14cm

Largest sphere is curved out from cylinder

Thus diameter of sphere = diameter of cylinder

Diameter of sphere (d) = 2 x 7 = 14cm

Volume of a sphere = `4/3pir^3`

`=4/3xxpi(7)^3`

`=(1372pi)/3`

= 1436.75cm^{3}

∴ Volume of sphere = 1436.75cm^{3}

Is there an error in this question or solution?
