Question

If the radius of sphere is doubled its volume become__time the volume of orginal sphere

Answer 1

Answer:

Let the radius of Sphere Before= r

so the Volume of sphere before= 4/3 πr^3

After increasing

the Radius becomes = 2 × r = 2r

So,

the volume of sphere= 4/3 π (2r)^3

= 4/3 π 8r^3

So, the volume becomes 4/3 πr^3

= --------------------

4/3 π 8r^3

Now,

1/8

So, We can say that the volume becomes the 8 times of the initial one
