Question

the diameter of the moon is 1/4 of earth find ratio of volume and surface? ​

Answer 1

Answer:

let the diameter of earth = x

radius = x/2

diameter of moon = 1/4x

radius = 1/4x /2 = 1/8 X

volume of earth = 4/3πr^3

volume of moon = 4/3π r^3

ratio = 4/3πr^3 / 4/3π r^3

ratio= r^3 /r^3

= (x/2)^3/(1/8x)^3

= x/2/ 1/8x

.

= 1:4
