    (10/7 PI) = 4.4879895051 * 57.2957795131 = 257.1428571429 degrees

    sector area = radius^2 * PI * (central angle / 360)

    sector area = 338.56 * 3.14159 * 0.7142857143

    sector area = 759.73 square meters

    Area = Pi r^2 * C/360 =

    where C is central angle in degress

    10 pi / 7 = 257.14

    Area = 3.14 * (18.4) ^2 * 257.14/360 = 759.3
