Question

The volume of a sphere of diameter $d$ is:

• A. $\frac{\pi d^3}{3}$
• B. $\frac{\pi d^3}{6}$
• C. $\frac{2\pi d^3}{3}$
• D. $\frac{\pi d^3}{4}$

Answer 1

The correct option is B $\frac{\pi d^3}{6}$

Volume of sphere $=\frac{4}{3}\left(\pi \right)r^3=\frac{4}{3}\left(\pi \right){\left(\frac{d}{2}\right)}^3=\frac{\pi d^3}{6}$
