Question

The volumes of two spheres are in the ratio of 8:343 What is the ratio of their radii?​

Answer 1

Answer:

2:7

Step-by-step explanation:

Let the volumes of two spheres be = V and v

V ; v =8 : 343

=4/3π(R)³ : 4/3π(r)³

=4/3π( R)³/4/3π(r)³=8/343

(R)³\(r)³=√³ 8/√³343

R : r = 2 : 7

Answer 2

Answer - 2/7

Step-by-step explanation:

So, let the two circles have radius R and r

and we know that volume of sphere is 4πr³

than, 4πR³/4πr³ = 8/343 ( given)

now after dividing we get,

R³/r³ = 8/343

so the rato is 2/7

Hope you will satisfy with my answer thanks
