Question

ifbthe radius of the shere is doubled find the radio of the volume of the first sphere to that second sphere ​

Answer 1

Answer: 1 : 8

Step-by-step explanation:

Volume of first Sphere:

Volume of sphere = $\frac{4}{3}$πr³

Volume of second sphere:

If radius is doubled, Volume = $\frac{4}{3}$π(2r)³ = $\frac{4}{3}$π8r³

Ratio = $\frac{4}{3}$πr³ : $\frac{4}{3}$π8r³

= 1 : 8

[Since, everything gets cancelled out and only 1 and 8 are left.]
