The answer is 36π or approximately 113.1 cm.
Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
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 13ft is about 2,123.7ft2
The surface area of a sphere with a radius of 2 is about 50.27 units2
The surface area of a sphere with a radius of 5m is 314.2m2
Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
Formula: 4πr2 Surface Area = 113.09734 units2
The surface area of a sphere with radius 6 is: 452 square units.
