    The area of the circle is determined through the equation,

    A = πr²

    Plug in the value of area

    36 in² = πr²; r = 3.385 in

    The formula for the circumference of the circle is,

    C = 2πr

    Substitute the value of radius,

    C = 2π (3.385 in) = 6.77π in

    Thus, the circumference of the circle is 6.77π inches.
