Ratio of volumes is 53 to 83 which is 125 to 512
Remember for ratios
Linear is a:b
Area is a^2:b^2
Volume is a^3:b^3
The radii are linear as a:b :: r :R :: 5:8
Hence the Volume ratios are a^3:b^3 :: r^3:R^3:: 5^3:8^3 :; 125: 512
Hence their volume ratios are 5:8::125:512
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*
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
It is 8 : 343.
3/4
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
729/8
27:343 *apex sucks*
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
3^3 / 5^3 = 27 / 125
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.
3/4
It is 27 : 343.
