A.1.7 m-1B.300 m-1C.500 m-1D.0.6 m-1
the answer is D. 0.6 m-1
Surface area= 432 m2
Volume= 864 m3
Answer: 0.5 m -1
0.6 is the surface area to volume ratio.
0.5m-1
Perhaps if you read the question properly, you would not have to ask the question!
The ratio is 1/2 square meter per cubic meter.
It is not possible to have a sphere with a surface are of 300 metres squared and a volume of 500 metres cubed. A surface area of 300 sq metres would imply a volume of 488.6 cubic metres or a shape that is non-spherical!
0.6 m-1 is the ratio of surface area to volume for a sphere.
0.6 is the surface area to volume ratio.
It appears to be: 3 to 5
0.5m-1
0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.
0.4 m-1 (Apex)
-- 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)
Perhaps if you read the question properly, you would not have to ask the question!
The ratio is 300 m2/500 m3 = 0.6 per meter.(Fascinating factoid: The sphere's radius is 5 m.)
The ratio is 1/2 square meter per cubic meter.
It is not possible to have a sphere with a surface are of 300 metres squared and a volume of 500 metres cubed. A surface area of 300 sq metres would imply a volume of 488.6 cubic metres or a shape that is non-spherical!
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
