Q. The ratio of the volumes of two cones having equal heights is 25 : 49. The ratio of their radii is:
β
Correct Answer: (A)
5 : 7
Explanation: Volume ∝ r² when heights are equal. Radius ratio = √(25 : 49) = 5 : 7.
Explanation by: Mr. Dubey
Volume ∝ r² when heights are equal. Radius ratio = √(25 : 49) = 5 : 7.
