The suface area of a sphere with a radius of 7 meters is 615.75m2
153.9 units squared.
Surface area of a sphere = 4 x (pi) x (radius)2
Surface area of a sphere = 4πr2
The formula to calculate the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7.5 meters into the formula, we get 4π(7.5)^2 = 4π(56.25) = 225π square meters. Therefore, the surface area of a sphere with a radius of 7.5 meters is 225π square meters, or approximately 706.86 square meters.

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
