QQuestion

If the volume of a right circular cone is V cubic unit, the base area is A sq. unit and the height is H unit, then find the value of \frac{AH}{3V}

Exam-ready answer 02 Mark

Answer

V = 1\over3πr²H

or, V = 1\over3AH   (∵ A = πr²)

or, 3 = \text{AH}\over \text{V}

or, \text{AH}\over \text{3V} = 1
