Question

Volume of one big sphere is equal to the volume of 8 small spheres. Calculate the ratio of volume of big sphere to volume of small sphere.

hintHint:

Volume of sphere is equals 4 over 3 pi r cubed

The correct answer is: 8:1


    Explanation: 
    • We have given volume of one big sphere is equal to the volume of 8 small spheres
    • We have to find the ratio of volume of big sphere to volume of small sphere
    Step 1 of 1:
    We have given volume of one big sphere is equal to volume of 8small spheres.
    Let volume of big sphere be denoted as Vb and volume of small sphere be denoted as Vs
    So,
    table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell V subscript b equals 8 V subscript s end cell row cell V subscript b over V subscript s equals 8 over 1 end cell end table
    Therefore the ratio is 8:1
