Question

circumference of the base of a right circular cone are in ratio 3:4 and their volumes are in ratio 9:32 then the ratio of the height is​

Answer 1

Answer:

1:2

Step-by-step explanation:

I assume there are two cones. The radii are in ratio 3:4.

Let the radii be 3k and 4k respectively. Let the volume be 9m and 32m respectively. Volume of a right circular cone V = (pi × r × r × h) ÷ 3 so, h = (3 × V) ÷ (r × r). Hence, h1/h2 = 1/2.
