Question

Apollo 8 was the first manned spacecraft to orbit the moon at an average altitude of 185 km above the moon's surface. Determine an equation to model a single circular orbit of the Apollo 8 command module if the radius of the Moon is 1,740 km. Let the center of the moon be at the origin.

Answer 1

I have that question on online work I don't see that answer choice the guy below gave but the correct one I got was

x^2+y^2=3,705,625

Answer 2

Apollo 8 was the first manned spacecraft to orbit the moon at an average altitude of 185 km above the moon's surface.

an equation to model asingle circular orbit of the Apollo 8 command module if the radius of the Moon is 1,740 km,will be :

x^2 + y^2 = 1925^2
