    Area: 28.25

    Step-by-step explanation:

    Area = Circumference^2

    4 (pi)

    18.84^2 = 354.9456

    4 (pi) = 12.5663706144

    354.9456 : 12.5663706144 = 28.2456733843

    Rounded to the nearest hundreth, the 5 in the thousandths place converts the 4 in the hundreths place into 5.
