Area is pi(r)^2 So 3.14=3.14(r)^2
Divide each side by 3.14
1=r^2
Then take the square root of each side
1=r
The radius is 1.
I assumed that by "3.14" you simply meant pi, so I used 3.14 for pi. If the area was actually exactly 3.14 and not pi, the answer would be very close to one, but not exactly. If this is the case you will get the radius to be roughly .999746489.
