Question

The radius of a sphere is `7/2` cm. The volume of the sphere is ______.

Options

• `231/3` cu cm

• `539/12` cu cm

• `539/3` cu cm

• 154 cu cm

Answer 1

The radius of a sphere is `7/2` cm. The volume of the sphere is `bbunderline(539/3  "cu cm")`.

Explanation:

Given that,

Radius of sphere, r = `7/2` cm

We know that,

Volume of Sphere = `4/3πr^3`

Volume = `4/3 xx 22/7 xx 7/2 xx 7/2 xx 7/2`

Volume = `(11 xx 7 xx 7)/3`

∴ Volume = `539/3  "cm"^3`
