The volume of a spherical snowball melts at the rate of 2n cm /hr. It melts symmetrically in a perfect physical universe such that the snowball is always a sphere, How fast is the radius of the snowball changing with r = 10? You may need the following: the volume V(r) of a sphere with radiusr is given by V(r) = rr. You need to show work to receive marks. The volume of a spherical snowball melts at the rate of 2n cm /hr.
