Surface area of sphere = 4r
4 xπ x r2 = 452.39 cm2
r2 = 452.39/(4) = 36.01831210191 cm2
r = sqrt(36.01831210191) = 6 cm(approximately)
And volume is given by V = 4πr3 = 4 x π x 63/3 cm3 = 905.46912199289 cm3

A sphere with a surface area of 324pi cubic inches has a volume of: 3,054 cubic inches.
depends on the shape... if its a sphere or a prism or what. You'll get different answers because they have different surface area to volume ratios. Sphere will give you the biggest volume for a given surface area.
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.
Well, first of all, that's no sphere.-- A sphere with surface area = 300 has volume = 488.6.-- A sphere needs surface area of 304.6 in order to have volume = 500.But this is just a ratio exercise, not a geometry problem, so we'll just use the numbersgiven in the question. It's just some sort of wacky humongous paramecium:Surface area = 300Volume = 500Ratio of (surface area)/(volume) = 300/500 = 0.6 .
0.6 is the surface area to volume ratio.
