    The formula for the area of the circle is equal to pi * r^2. Since area is known, we can find the value of r.

    A = pi * r^2

    153.86 = 3.14 * r^2

    r^2 = 153.86/3.14

    r = 7 inches

    The formula for the circumference of a circle is 2*pi*r

    C = 2*3.14*7

    C = 43.96 inches.

    Thus the answer is

    A) R = 7 inches ... C = 43.96 inches
