The surface area of a cone is A= \pi r^{2}+ \pi r \sqrt{ h^{2} + r^{2} }. Lateral area is A= \pi r \sqrt{ r^{2} + h^{2} }. Here \sqrt{ h^{2} + r^{2} } is a slant height. 

Using this information we can write that 60 \pi =10 \pi r and r=6 cm

The volume of the sphere is given by V= \frac{4}{3} \pi r^{3}. If we calculate it, we'll obtain V=288 \pi
