The radius of sphere A is twice that of a sphere B Find The ratio amoung their surface areas THE ratio amoung their volumes

Answer 1

Step-by-step explanation:

$\frac{4}{3} \pi {r}^{3} ratio \frac{4}{3} \pi( {2r})^{3}$

The 4/3 and the pi will be cancelled out leaving r^3:8(r^3)

the two radius will cancel out leaving 1:8
