Question

the base radii of two circular cones of the same height are the ratio 3:5 the ration of their volumes are​

Answer 1

Answer:

Let r1and r2 be the radii of two cones and V1and V2 be their volumes. Let h be the height of the two cones . Then,

V1 = 1/3πr1^2 h and V2 = 1/3πr2^2h

Therefore,

V1/ V2 = r1^2/r2^2= 9/25

Hence, the ratio of the volumes of two cones is 9 : 25.

Hope this is helpful for you.
