The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.

Surface area of sphere: 4*pi*12^2 = 576*pi square m

The formula for the surface area of a sphere is 4 (pi) r2For a radius of 4, the surface area is4 (3.1416) (4)2 = 4 (3.1416)(16) = about 201.06 square units

Area = 4*pi*r^2
