Find the rate of change of the volume of a ball with respect to its radius `rdot` How fast is the volume changing with respect to the radius when the radius is 2cm?

Explanation

` v=frac{4}{3} pi r^{2} frac{d v}{d gamma}`


`=frac{4 times 3 times pi gamma^{2}}{3} `


` =4 pi gamma^{2} `


`=4 times 3.14 times(4) =50.24 `
