i take it you mean what is the radius of a circle with an area of 22
22=pir^2
22/pi=r^2
7=r^2
r=sqrt(7)

Area = 22
pi r^2 = 22
r^2 = 22/pi
= 22/22/7
= 22/22 * 7
r^2 = 7
r=square root of 7
radious of the circle with area 22 = square root of 7

22 / pi=7.002
square root of 7.002 is about 2.646
So the radius of the circle is 2.646
