Earth revolves around the sun in an elliptical orbit. However, for this problem, you can assume that the orbit is circular with a radius of about 9.3X10^7 miles.
a. At what speed in feet per second does the Earth travel around the sun?
b. An astronomer estimates the angle subtended by the width of the sun as 0.5 degrees. If this is the case, what is the approximate diameter of the sun?
I tried working this one out, but I'm sure I messed it up really bad. Something is way off in my answer...
Thanks for any help!
