The diameter of the moon is about 1/4 the diameter of earth find the ratio of their surface area

Answers (1)

Surface area is proportional to the square of the radius. Therefore the surface area is proportional to the square of the diameter.

Let the diameter of the earth be d, then then the diameter of the moon is d/4

The surface area of the moon/surface area of the earth

=\frac{\frac{d^2}{16}}{d^2}=\frac{1}{16}
