    Step-by-step explanation:

    The formula for circumfrance is 2 * (pi) * R and the formula for area is (pi) * R^2 or (pi) R-squared.

    Circumfrance is 25.12 so ...

    25.12 = 2 * (pi) R ... you want to find R because you need it to find the area

    R is about 4; it is 3.99797.

    You use the R that you goot from cirdumfrance to find area.

    Area = (pi) (4) ^2 = 50. 265

    or is you prefer a more precise answer, Area = 50.2145
