Question

Earth has a diameter of approximately 7,920 miles and a volume that is roughly 49 times the volume of the moon. Find the diameter of the moon ?

Answer 1

i cube root 1.01386 x 10^10 , right ?

Answer 2

Hold on I have to correct what I just posted

Answer 3

Sphere Volume = (4/3) * PI * r^3
Earth Volume = (4/3) * PI * 3,960^3
Earth Volume = 2.6012 x 10^11 cubic miles

Moon volume = earth volume / 49
Moon volume = 2.6012 x 10^11 cubic miles / 49
Moon volume = 5.308576583 x 10^9 cubic miles

5.308576583 x 10^9 cubic miles = (4/3) * PI * r^3
r^3 = 5.308576583 x 10^9/[(4/3)* PI]
r^3 = 1.267329305 x 10^9
r = 1082.1725 miles

diameter = 1082.1725 miles times 2 =
= 2,164.345 miles

Answer 4

Sorry I messed up the previous calculation.
I'll delete it.
