Here A = 113.04 sq.ft. Also .
So,
or
Thus reqd. value of r is 6 ft.

A=PI*r2
113.04=(3.1415)*r^2 [Is the "r" value raised to the 2nd power?]
113.04/3.1415=r^2
35.9828=r^2
sqrt(35.9828)=sqrt(r^2)
5.998=r
.
Check by plugging all of the variables back into the original equation.

if A=113.04sq ft and =3.14 what is r
Solve the formula for r and plug in your numbers.

(you don't need to use + or - because you can't have a negative radius.)
A=113.04 ft^2 and =3.14

Happy Calculating!!!
