Question

What is the formula for the volume of a right circular cone?

(a) \(\frac {1}{3}\)πr^3h

(b) \(\frac {1}{3}\)πr^2h

(c) \(\frac {1}{2}\)πr^2h

(d) \(\frac {1}{2}\)πr^3h

The question was posed to me by my school principal while I was bunking the class.

I'd like to ask this question from Surface Area and Volume of Different Solid Shapes in division Surface Area and Volumes of Mathematics – Class 10

Answer 1

The correct answer is (b) \(\frac {1}{3}\)πr^2h

Easiest explanation: Volume of right circular cone = \(\frac {1}{3}\)πr^2h

Where ‘r’ is the radius of the base and ‘h’ is the height of the right circular cone.
