The ratio of volume and surface area of sphere 14:3 find the radius of sphere​

Answer»

Step-by-step EXPLANATION:

\frac{volume \:of \:sphere }{surfce \: area}  \:  \:  =  \frac{14}{3}  \\   =  > \:  \frac{ \frac{4}{3}\pi {r}^{3}  }{4\pi {r}^{2} }  \:  \:  =  \:  \:  \frac{14}{3}  \\  =  >  \frac{r}{3}  \:  \:  =  \:  \:  \frac{14}{3 }  \\  =  > r = 14 \: cm
