Ratio of total surface area of hemisphere to that of sphere ?

The surface area of a sphere is the same as the curved surface area of a cone having the radius of the base as 120 cm and height 160 cm. Find the radius of the sphere.

A right circular cylinder circumscribes a sphere of radius r.Find the ratio of the surface area of the sphere to the curved surface area of the cylinder.
