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

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.
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 is 4 pi R2A = 4 pi (5)2 = 100 pi = 314.16 square meters (rounded)
The surface area of a sphere with a radius of 2 is about 50.27 units2

The surface area of this sphere is about 11310 m2The formula for the surface area of a sphere is SA = 4 (pi)r2For r = 30 m, this is 4(3.1416)(30)2 = 4 (3.1416)(900) = 11309.7 square meters
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
SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
