Apollo 8 orbited the moon in a circular orbit. Its average altitude was 185 km above the moon's surface. Create an equation to model the path of Apollo 8 using the center of the moon as the origin. Note that the radius of the moon 1,737 km.
a. x^2+y^2=34,225
b. x^2+y^2=2,408,704
c. x^2+y^2=3,017,169
d. x^2+y^2=3,694,084
I am a little confused with this. Please help ;)

What is difficult here?
Equation of a circle:
x² + y² = r²
x² + y² = 1,737²
x² + y² = 3,017,169
Answer c.posted by Bosnian

Correction.
I forgot altitude.
R = r + 185 = 1,737 + 185 = 1,922
x² + y² = R²
x² + y² = 1,922²
x² + y² = 3,694,084
Answer d.
