The surface area of any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .
1500pi
Surface area of half a sphere = 2*pi*radius2 Surface area = 200*pi = 628.3185307 square units.
The Surface area of a sphere is 4*pi*r2 where r=radius So, 4*pi*102= 1256.63706 inches2
Area = 4*pi*102 = 400*pi square units
