Question

What is the volume of this sphere?

Answer 1

The figure shows a sphere with diameter 28 cm.

Radius = half of diameter

Radius = half of 28= 14 cm

The formula for volume of sphere is given by :

$V= \frac{4}{3} \pi r^{3}$

where r is radius of sphere.

Plugging the value of pi =3.14 and r=14cm in the formula,

$V= \frac{4}{3} (3.14) (14)^{3}$

On solving we get Volume =11488.21 cm³

Answer 2

11488, 4pi*r^2/3 is the formula
