Answer:

The surface area of a sphere is given by SA = 4πr2 where r is the radius of the sphere. The total surface area of hemisphere = 2πr2+ πr2 = 3πr2 square unit. Curved surface area of hemisphere = 2πr2square units.

Answer:

The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 π r2 = 1062. Solve for r.

Step-by-step explanation:

Similarly, the volume of a ball enclosed by a sphere of radius R is (4/3)*Pi*R3. And the formula for the surface area of a sphere of radius R is 4*Pi*R2.
