    Answer:

    The area of the circle is”:

    A = 1017.36 in²

    The circumference of the circle is:

    C = 113.09 in

    Step-by-step explanation:

    Given

    r = 18 in

    We need to determine the area and circumference of the circle

    Using the formula to determine the area

    A = πr²

       = 3.14 × (18)²

       = 3.14 × 324

       = 1017.36 in²  (Rounded to the nearest 0.01 or  the Hundredths Place)

    Thus, the area of the circle is”:

    A = 1017.36 in²

    Using the formula to determine the circumference.

    C=2πr

      = 2 × 3.14  ×  18

      = 113.09 in

    Thus, the circumference of the circle is:

    C = 113.09 in
