Question

7. The diameter of the moon is approximately one fourth of the diameter of the earth.
Find the ratio of their surface areas.​

Answer 1

Step-by-step explanation:

earth diameter=moon diameter

d=1/4d

so area of earth=area of moon

4pi.(d/2)²=4pi.(d/8)²

d²/4=d²/64

1:64

Answer 2

Answer:Sm:Se=1:16

Step-by-step explanation:

Sm:Se=1:16

You can tell by looking at the ratio that the surface area of earth is 16 times that of moon. Which makes sense.
