Question

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

Answer 1

Answer:

let's take the diameter of earth be d

so diameter of moon is d/4

1. area of earth = 3.14r²

• = 3.14 d²/4

2 area of moon = 3.14r²

= 3.14d²/16

now, ratio of area of moon to earth = (3.14d²/16)/(3.14d² / 4)

Ans = 1/4
