Question

the voulumes of two spheres are in the ratio 8:27 the ratio of their surface areas is​

Answer 1

Answer:

Ratio of surface areas is :- 4:9

Hope it helps

Answer 2

Answer:

let,

radius of first sphere be r1

radius of second sphere be r2

4/3πr1³:4/3πr2³=8:27

r1³: r2³=8:27

27r1³=8r2³

3r1=2r2

r1/r2=2/3

ratio of surface areas

4πr1²:4πr2²

=r1²:r2²=(r1/r2)²=(2/3)²=4:9
