Question

By which kultiplying the surface of sphere,the volume of sphere can be obtained

Answer 1

Solution :

Let radius of a sphere = r

Surface area of the sphere( A ) = 4πr²

volume( V ) = ( 4/3 )πr³

Let x should be multiplied by

surface area of sphere to get volume

x × A = V

=> x = V/A

=> x = [ (4/3)πr³ ]/( 4πr² )

After cancellation , we get

= r/3

Required number should multiplied

= x = r/3
