Surface area of a sphere = 4 x (pi) x (radius)2
Surface area of a sphere = 4πr2
615.75216 m2
Surface area = 201.06 meters2
Area = 4 x pi x radius squaredAnswer is 61575.2m2
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 .
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
Surface Area of Sphere = 4*pi*r2 = 4*pi*22 = 16*pi
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters
100 x pi m2
It is: 4*pi*62 = 144*pi square meters
