Question

When the radius of a sphere is doubled the volume of the sphere becomes​

Answer 1

Answer:

if the radius of a sphere is double the volume of the sphere it become 8 times

xd....

Answer 2

Answer:

8 times

When the radius of sphere is doubled its volume gets increased 8 times.

Step-by-step explanation:

Let the radius of sphere be 'r'. Then,

We know that,

Volume of sphere = 4π(r)^3

Now,

When radius is doubled,

r = 2r

Volume of new sphere = 4π(2r)^3

Volume of new sphere = 4π8(r)^3

Volume of new sphere = 8(4π(r)^3)

This, can be also written as :

Volume of sphere with doubled radius = 8(Volume of original sphere)

Hence, when the radius of sphere is doubled its volume gets increased 8 times.
