The radius is 3.45
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...
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
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
The surface area of a sphere with a radius of 5m is 314.2m2
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 2 is about 50.27 units2
To calculate the surface area of a sphere, you first need to determine its radius. Once you know the radius, you need to square it, or multiply it by itself. Next, you will need to multiply it by 4. Finally, you will multiply that number by pi, or 3.14.
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
The surface area of a sphere with a radius of 12 units is about 1,809.6 units2
