How does a sphere shape differ from other shapes?
For a given area, the biggest volume you can enclose is a sphere. A sphere has the best volume-to-area ratio.
What is the ratio of the surface area of a sphere with radius 2 ft to the surface area of a sphere with radius of 5 ft?
a. 2 to 5.
What is the ratio of the surface area of the sphere to its volume?
The surface area of a sphere with radius 'R' is 4(pi)R2 The volume of the same sphere is (4/3)(pi)R3 . Their ratio is (4 pi R2)/(4/3 pi R3) = (12 pi R2)/(4 pi R3) = 3/R
Ratio of a cone to cylinder to sphere?
4 : 8 : 6 in terms of letters in their names. If you wanted the ratio of some other characteristic you should have specified which.
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.
