Find total surface area of a solid hemi-sphere of radius 7cm.

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

Given a sphere,a cone is constructed so that the cone and the sphere have the same volume,but the total surface area of the cone is k xx that of the sphere,where k is determined so that there is a unique cone satisfying this property.Then k equals:

As shown in the adjacent figure, a sphere is placed in a cylinder. It touches the top, bottom and the curved surface of the cylinder. If radius of the base of the cylinder is 'r', (i) what is ratio of the radii of the sphere and the cylinder? (ii)what is the ratio of the curved surface area of the cylinder and the surface area of the sphere? (iii) what is the ratio of the volumes of the cylinder and the sphere?

The total surface area of a sphere is 8pi square unit. The volume of the sphere is
