Question

the volumes of two cones are in the ratio 1 : 10 and the radii of the cones are in the ratio 1 : 2. what is the ratio of length of wire.​

Answer 1

Answer:( i think that ratio of height need to be calculated).

The ratio of the height of the cines will be 2:5

Step-by-step explanation:

Let the two radius be r1 and r2

And height will be h1 and h2

Since the ratio of volume is 1:10

thus V1/V2=1/10 which will give

r1^2 h1 / r2^2 h2 =1/10 ---(1)

and r1 /r2 = 1/2 ( given ) thus putting in 1 gives h1/h2 = 2/5

Thus the required ratio of height will be 2/5
