I. mass of earth (using kepler's third law):
1. let's examine the earth - moon system. if the moon orbits the earth once every
27.3 days, what is this orbital period (p) in years? (hint: multiply or divide by 365)

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
