Answer 1

Dear student,

Earth diam = 4 x 2r= 8rRadius = 4rsurface areaof moon.....1 = 4pir2surface areaof earth.....2 = 4pi(4r2)= 4pi x 16 x r2= 64pir2surface areaof moon.....1 = 4pi2surface areaof earth.....264pi2 = 1 : 16

 

 

Best wishes!

 

Answer 2

ratio is
let the diameter of moon is 2
than diameter of Earth is 8
area of moon is π
area of Earth is 16π
ratio is 16:1
