The area of a circle equation is $$A = \pi*r^2$$

anonymous · Answer

so if the area is 112.07, that means 112.07 = pi*r^2

anonymous · Answer

112.07 divided by pi equals 35.673
so 35.673 = r^2

anonymous · Answer

Can you answer it from there?

anonymous · Answer

square root it

anonymous · Answer

yup, so sqrt(35.673) is gross looking but a calculator gets you to 5.97269

anonymous · Answer

from here you round to the nearest hundredth and get to your answer. done and done
