Volume of a cylinder = \(\pi * radius^2 * height\)

Volume of a cone = \(\frac{{\pi * radius^2 * height}}{3}\)

In both cases we donot know the radius, enough information is not given

We don´t know the area of the base. Therefore, we cannot calculate the volume of the solids and the answer is D.

Hello all,

For this question,

We have volume of cylinder = pi* r square* 10
Volume of cone= ( pi* r square *10 )/3

r cannot be zero and is always >0, then if we assume r value as 0.5 or 1, in both the cases volume of cylinder would be greater. Then I would put quantity A is greater. Can't I follow this approach? If I don't consider this assumption, then option D would be the right answer.

I took these r value assumptions because we generally test the quantitative comparison questions assuming some values for 'x' or any other variable.
