    area of a circle = 1808.64meters²

    Step-by-step explanation:

    given that,

    π = 3.14

    circumference = 150.72meters

    calculate the area of the circle.

    to calculate the circumference of a circle

    recall,

    circumference of a circle = 2πr

    circumference of a circle = 2 x 3.14 x r

    circumference of a circle = 6.28r

    150.72meteras = 6.28r

    divide both sides by 6.26

    150.72meters/6.28 = 6.28r/6.28

    24meters = radius

    radius = 24 meters

    now to calculate the area of the circle

    recall the formulae for finding the area of a circle is given to be = πr²

    area of a circle = πr²

    area of a circle = 3.14 x (24) ²

    area of a circle = 3.14 x 576meters²

    area of a circle = 1808.64meters²
