Question

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

Answer 1

Step-by-step explanation:

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