Question

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

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

Answer 1

The correct option is C $120\pi {\text{cm}}^3$

Given: Height = $10$ cm, Radius =$6$ cm

Volume of the right circular cone$=\frac{1}{3}\pi r^{2}h=\frac{1}{3}\times \pi \times 6\times 6\times 10=120\pi c{m}^3$
