    Answer:

    Radius: 4in

    Circumference: 8π or 25.12 in^2

    Step-by-step explanation:

    Since Diameter is 2*radius, we can divide the diameter by 2 to get the radius. The radius is 8/2 = 4in.

    The formula for circumference is 2πr or simply πd. Since we have the diameter, we just need to multiply it by π for the circumference.

    In this case, we are using 3.14 as π. So the circumference is approximately 3.14*8 = 25.12
