Question

If the radius of a sphere is doubled, which is the ratio,of the volume of the first sphere to that of the secon sphere? ​

Answer 1

Answer:

ratio=1:8

Step-by-step explanation:

let original radius be r

so the original volume=4/3π(8r^3)

New radius = 2r

so, New radius=4/3π(2r)^3=4/3(8π)^3

Ratio=4/3π^3divided by 4/3π(8r)^3 then cancelled =1/8 in ratio=1:8
