Volume= 4/3 * pi * r^3 (where * means multiply and ^3 means cubed
So for a sphere of radius 9 Vol = 4/3 * pi * 729 = pi * 972 = 3,053.628 cubic units.
Surface area = 4 * pi * r^2 (where ^2 means squared
So for a sphere of radios 9, the SA = 4 * pi * 81 = pi * 324 = 1017.876 square units

Relation between volume radius and surface of sphere?
Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3
When was the formula for the area and volume of a sphere created?
Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed
Surface-area-to-volume ratio in nanoparticles?
Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r: The surface area of the sphere will be 4πr2 The volume of the sphere = 4/3(πr3) Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
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.

What is the surface area of sphere with radius 13ft?
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
What happens to the surface area of a sphere if its radius is doubled?
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
As the radius of a sphere gets larger which of the spheres measurements increases more the surface area or the volume?
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
