Question

The volume of a right circular cone of height $8$ cm and radius of base $3$ cm is

• A. $12\pi c{m}^3$
• B. $24\pi c{m}^3$
• C. $48\pi c{m}^3$
• D. $72\pi c{m}^3$

Answer 1

Answer: (B)

$24\pi c{m}^3$

Given,
Radius of cone $=3$ cm
Height of cone $=8$ cm
$\therefore$ Volume of cone $=$ $\frac{1}{3}\pi r^{2}h$
$=$ $\frac{1}{3}\pi \times 3^2\times 8$
$=$ $24\pi$
