Find the volume of a sphere of diameter 21 cm (Use $ π = \frac{22}{7})$

4851 cm³

We know that,

Volume of the sphere = \(\frac{4}{3}\)πr³

We have,

Diameter of the sphere = 21 cm

then the radius of the sphere = \(\frac{21}{2}\)  

Volume of the sphere = \(\frac{4}{3}\)πr³

= \(\frac{4}{3}\) × \(\frac{22}{7}\) × (\(\frac{21}{2}\))³

= 4851 cm³
