Answer 1

Answer:

‍⚖Rural areas are areas which are not towns or cities. They are often farming or agriculturalareas. These areas are sometimes called "the country" or "countryside". Rural is the opposite of urban, which means places such as cities where buildings and places where people work and live are all close together.

Answer 2

Answer:

here is your  answer

Step-by-step explanation:

ratio of surface areas

4 πr^2/4πr^2

surface area 1 / surface area 2 = r1^2 / r2^2

= 4/9 is  the ratio of surface areas

ratio of volumes

4/3πr^3 / 4/3πr^3

volume1 / volume2 = r^3 / r^3

= 8/27 is the ratio of their volumes
