Formula for Area of circle :
------------------------------------------------------
Area of a circle = πr²

------------------------------------------------------
Find radius :
------------------------------------------------------
1661.06 = 3.14 x r²
r² = 1661.06 ÷ 3.14
r² = 529
r = √529
r = 23 unit
