Question

Volume of a right circular cone of radius ${}^{\prime }r{}^{\prime }$ and height ${}^{\prime }h{}^{\prime }$ = .

• A. $\frac{1}{3}\pi r^{2}h$
• B. $\frac{1}{2}\pi r^{2}h$
• C. $\pi r^{2}h$
• D. $\frac{1}{3}\pi rh$

Answer 1

The correct option is A $\frac{1}{3}\pi r^{2}h$

Given solid: Right circular cone
Radius: $r$
Height: $h$

Volume of the right circular cone
$=\frac{1}{3}\times \text{Volume of cylinder}$
$=\frac{1}{3}\pi r^{2}h$
