Question

The diameter, D, of a sphere is 7.4mm. Calculate how he spheres volume, V.

Answer 1

Given :

The diameter D of sphere is 7.4 mm .

To Find :

The volume of sphere.

Solution :

Radius of sphere is r = D/2 .

r = 3.7 mm .

We know, volume of sphere is given by :

`V = (4\pi r^3)/(3)\\\\V = (4* 3.14 * 3.7)/(3)\ mm^3\\\\V = 15.5 \ mm^3`

Hence, this is the required solution.
