Question

the diameter of moon is approximately 1/4 of diameter of earth. find the ratio of their volumes.

​

Answer 1

Step-by-step explanation:

let's diameter of earth =x

so diameter of moon =x/2

hence

1/x•x/4•x/8. (note • mean multiple)

Ratio of surface area =surface area of Moon/surface area of earth

4π(Radius off moon) ²

4π( Radium of earth) ²

=x²/8²/x²/2²

=x²/64•4/x²

=1/16
