    Step-by-step explanation:

    The formula for circumference of a circle is:

    C = 2πr, where π = 3.14 and r = the radius

    The formula for area of a circle is

    A = πr²

    First, using the formula for circumference, you can solve for 'r':

    53.42 = 2πr or 53.42 = 6.28r (divide) r = 8.5

    Now, use the value of 'r' to solve for area:

    A = π8.5² or 3.14 (8.5) ² = 226.9 in²
