a. 2 to 5.

SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24

You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2

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 .
