Answer
3.37 feet
10.59 feet
5.97 feet
35.67 feet

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

Can you answer it from there?

Answer 5

square root it

Answer 6

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

Answer 7

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