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 .
Area = 4*pi*r^2 4*pi*(7 meters)^2 = 615.75 meters^2
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters
The surface area of a sphere with a radius of 2 is about 50.27 units2
