So the area of a circle formula is $\pi$ r^2
so...
706.9=pi r^2, i want to get rid of pi, get the r isolated
225.01=r^2
so now we square root
15.0000

You have to make the fraction into an integer. the simplest version of a ratio involves the smallest possible integers. therefore, 5:2.5 will equal 10:5 (you multiply both sides by 2). 10:5 cancels down to 2:1. hope this helped :)
