1. The problem statement, all variables and given/known data 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. 2. Relevant equations c= (2)(pi)(r) 3. 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. heres 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?
