Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
Formula for calculating the area of sphere is : 4 * pi * r * r
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.
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
Formula: 4πr2 Surface Area = 113.09734 units2
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed
The surface area of a 14-inch sphere is 615.75 square inches.The formula for the surface area of a sphere is 4*pi*r2 where r=radius
Yes and its formula is: 4*pi*radius squared
Surface area of a sphere = 4 x (pi) x (radius)2
The surface area is about 314.16 cm2The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 cm, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 cm2*Do not confuse the sphere's surface area formula SA = 4 (pi) r2 withthe formula for the volume of the sphere, which is V = 4/3 (pi) r3
