A neighborhood park is circular in shape. One sector of the park needs repairing, so officials would like to block off that portion with barricades. The area of the sector is 45 yd2, and 2004-05-03-07-00_files/i0220001.jpg. Find the length of one side of the barricades (i.e., the radius of the circle).

missing info is theta = 72 degrees |dw:1591343560487:dw| area of a whole circle = pi * r^2 area of sector with angle theta in degrees = (theta/360) * pi*r^2 you have area and theta, solve for r
