Homework Statement
the problem asks to find the distance from the sun to a planet. the only information the question gives the the orbital period of 27 years and asks for the answer in km.
Homework Equations
c= (2)(pi)(r)
The Attempt at a Solution
assuming the planet revolves around the sun, i was assuming this is a simple problem using the circumference of a circle and solver for r to get the radius which is also the distance to the sun. here's my attempt.
c=(2)(pi)(r)
27=(2)(pi)(r)
r= 27/(2)(pi)
r= 4.29
thats my solution, but is seems really close to the sun, 4.29 km. have i done something wrong? can someone help?
