Question

The volume of 2 spheres is in the ratio 125:64 find the ration of their radii

Answer 1

Answer:  We have,

[tex]\frac{V_{1} }{V_{2}} = \frac{125}{64}  \\\ \frac{4\pi \frac{R^{3} }{3} }{4\pi \frac{r^{3} }{3} }=\frac{125}{64} \\\frac{R^{3} }{r^{3} } = \frac{125}{64}  \\\\frac{R}{r} = \frac{5}{4}[\tex]
