the volume is scale factor³
Take the square root of the volume ratio

[tex] \sqrt{ \frac{27}{125} } [/tex] which is 
[tex] \frac{ \sqrt{27} }{ \sqrt{125} } [/tex]

[tex] \frac{3}{5} [/tex]

The ratio of their radii is 3 : 5

Using formula v of hemisphere= 2/3x22/7xr3
v of hemi a= r3= 12.8
                 = r   =2.3
v of hemi b= r3 = 59.6
                 =r    = 3.9
So the ratio is 2.3:3.9
