Question

The volume of a right circular cone of height $10$ cm and radius of base $6$ cm is

• A. $120$ $\pi$ cm${}^3$
• B. $90$ $\pi$ cm${}^3$
• C. $60$ $\pi$ cm${}^3$
• D. $180$ $\pi$ cm${}^3$

Answer 1

Answer: (A)

Given :
Radius of cone $=6$ cm
Height of cone $=10$ cm
$\therefore$ volume of right circular cone $=\frac{1}{3}\pi r^{2}h$
$=\frac{1}{3}\pi \times 6^2\times 10$ cm${}^3$
$\therefore V=120\pi$ cm${}^3$
