If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.
volume goes a radius cubed so (8/5) cubed = 4.096
ratio would also be 2 since the volume of a sphere is 4/3(pie)r(cubed) and since both 4/3 and pie are constants the variable is the radius of the spheres and as such the ratio of the radii would be equal to that of the volumes.

The similarity ratio of the two spheres can be found by taking the cube root of the ratio of their volumes. The volume of the first sphere is 20pi m^3 and the volume of the second sphere is 160pi m^3. The cube root of the ratio of their volumes is (160pi/20pi)^(1/3) = (8)^(1/3) = 2. Therefore, the similarity ratio of the two spheres is 2:1.
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
27:343 *apex sucks*
3^3 / 5^3 = 27 / 125
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
It is 8 : 343.
If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
volume goes a radius cubed so (8/5) cubed = 4.096
ratio would also be 2 since the volume of a sphere is 4/3(pie)r(cubed) and since both 4/3 and pie are constants the variable is the radius of the spheres and as such the ratio of the radii would be equal to that of the volumes.

Ratio of volumes is 53 to 83 which is 125 to 512
It is 27 : 343.
