Question

the valume of two spheres are in the ratio of 64:27. the ratio of their surface areas is​

Answer 1

Answer:

Step-by-step explanation:

volume of  a sphere = $\frac{4}{3}\pi r^{3}$

ratio of volume = $\frac{ r_{1}^{3}}{ r_{2}^{3}}$

therefore , $\frac{r__{1}}{r__2}$ $= \frac{4}{3}$

surface area = $4 \pi r^2$

ratio of surface area is = $\frac{16}9$
