Question

The radii of 2 spheres are in the ratio 1:2. Find the ratio of theVolumes.

Answer 1

let r1 and r2 be radii and v1 and v2 be vol

r1/r2=1/2

V=4/3 pi r^3

V1/V2=4/3 pi r1^3÷4/3 pi r2^3
V1/V2=r1^3/r2^3
V1/V2=(r1/r2)^3
=(1/2)^3
=1/8

Ratio of volume is 1/8.

pls pls mark as brainliest answer pls and follow me

Answer 2

1:8 is the ratio of volume
