Answer:Radius:

4inCircumference:

8π or 25.12 in^2Step-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
