Question

The volume of sphere having radius 21 cm is ( Π = 22/7) ​

Answer 1

Step-by-step explanation:

Volume of a sphere

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

$= \frac{4}{3} \times \frac{22}{7} \times 21 \times 21 \times 21 \: {cm}^{3}$

$= 88 \times 441 \: {cm}^{3}$

$= 38808 \: {cm}^{3}$

Answer 2

Answer:

Volume of sphereV=4/3πr³

Radius= 21 cm

π = 22/ 7

Volume of sphere = 4/3*22/7*21*21*21

=4/3 * 22* 21*21

= 4*22*7*21

= 88* 147

= 12936 cm3 ( answer)
