Question

The radius of a spher is 2r then the volume would be

Answer 1

the volume of a sphere is 4÷3πr^3
radius is 2r now volume=
4/3×2 πr^3= 8/3πr^3

Answer 2

HEY Buddy......!! here is ur answer

Given that : The radius of any sphere = 2r

As we know that :

The volume of a sphere = 4/3 πr³

Here, r = radius of the sphere which is 2r given in the question..

Now, according to the question :

Volume of the sphere = 4/3π(2r)³

=> Volume of the sphere = 32/3πr³

=> Volume of the sphere = 8×4/3πr³

It means when the radius of the sphere will be 2 times then it volume will be 8 times as the volume of old sphere.

I hope it will be helpful for you....!!
