Question

The volume of a Right circular cone of height 12 cm and base radius 60 cm is

• A. $12\pi$
• B. $36\pi$
• C. $72\pi$
• D. $144\pi$

Answer 1

Answer: (D)

$144\pi$

solution:

the volume of right circular cone is :

$V=\frac{1}{3}\pi r^{2}h$

h = 12 cm , r = 60 cm

$V=\frac{1}{3}\pi {60}^{2}12$

$V=144\pi$

hence the correct opt: D
