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 .
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters
100 x pi m2
Area = 4 x pi x radius squaredAnswer is 61575.2m2
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
To calculate the surface area of a sphere, you can use the formula ( A = 4\pi r^2 ), where ( r ) is the radius. For a sphere with a radius of 7 meters, the calculation would be ( A = 4\pi (7^2) = 4\pi (49) = 196\pi ). Approximating (\pi) as 3.14, the surface area is approximately ( 615.44 ) square meters.
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.
The radius is 3.45
Surface area = 201.06 meters2
615.75216 m2
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.
To calculate the surface area of a sphere use the formula - 4pr2 r being the radius of the sphere. and 'p' being pi 3.14...
A radius of a sphere is the distance from its centre to its surface. It is also half of the diameter. If you know the circumference of a circle, you can calculate its radius. Circumference divided by Pi divided by 2 = radius.
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
