Why is a sphere one of the strongest shapes to use in construction?

It has the lowest ratio of surface area to volume.


Why are water drops are spherical in shape?

For a fixed volume, a sphere is the shape with the lowest surface area to volume ratio. Surface tension is minimized when the drop forms a sphere, and molecules always tend toward the position which minimizes energy.


Why does a drop fall in a round shape?

For a fixed volume, a sphere is the shape with the lowest surface area to volume ratio. Surface tension is minimized when the drop forms a sphere, and molecules always tend toward the position which minimizes energy.




Does a basketball have a lot of surface to volume ratio?

No. A sphere has the smallest surface to volume ratio possible and a basketball is nearly spherical in shape (it has surface dimpling and seams).


What is the ratio of surface area to volume for a sphere with the following measurements surface area 588m2 volume 1372m3?

-- The ratio of 588 to 1,372 is 0.4286 (rounded) -- A sphere with surface area of 588 has volume closer to 1,340.7 . (rounded)



What is the ratio of surface area to volume for a sphere with the Surface area of 300m2 and a volume of 500 m3?

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 .


Why the dot of water is always sphere?

Surface tension is in equilibrium. The shape of a sphere has the highest volume to surface area to radius ratio. This shape is the lowest energy level a volume of liquid can have. Deforming it into another shape would involve an increase in surface area and an increase in the average radius.


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 what the ratio of surface area to volume for a sphere is?

1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio


What is the ratio of surface area to volume for a sphere with the surface area is 432m2 and volume is 864m3?

A sphere can either have a surface area of 432 m2 but not a volume of 864 m3, or it can have a volume of 864 m3 but not a surface area of 432 m2.


What is the ratio of surface area to volume for a sphere with the following measurements surface area 432m square volume 864m Square?

-- "864m square" is not a volume. "864m cubed" is a volume.-- A sphere can't have those measurements.If it's really a sphere with surface area of 432 m2, then its volume is 844.3 m3.If it's really a sphere with volume 864 m3, then its surface area is 438.7 m2.-- The answer to the question is: The ratio of 432 m2 to 864 m2 is 0.5 .-- If those are really an area and a volume, then the ratio of 432 m2 to 864 m3 is 0.5 per meter.


Can the surface to volume ratio of a sphere be the same as a cube?

Yes, if the side length of the cube is one-third of the radius of the sphere.



Surface area equals 300 m2 Volume equals 500 m3. What is the ratio of surface area to volume for a sphere with the following measurements?

If the shape is a perfect sphere, then the ratio of surface area to volume will always be: 4πr2 / 4/3πr3 = 3/r If the volume = 500m3, then we can say: 500m3 = 4/3πr3 375m3 = r3 r = 5∛3 m So the ratio of surface area to volume on that sphere would be 3 / (5∛3 m), or: 3∛3/5m



What happens to the surface area and volume ratio as the cell decreases in size?

The ratio of surface area to volume increases. The area of a sphere is proportional to its radius squared. Volume is proportional to radius cubed. As the radius increases, the volume increases more than the surface area. As the radius decreases, the volume decreases more than the surface area, so the ratio of surface area to volume increases.




Why is everything in space a sphere shape?

A sphere contains the most volume to surface area ratio there is and most things sought that shape when molten.



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
