while the area of the circle 
Since the diameter is the radius multiplied by 2, the radius of the circle is 8. So substituting 8 for r, the circumference is 2 ×
× 8, which is approximately 50.27 (rounded to the nearest hundredth) and the area of the circle would be
× 8². 8² is 64 so 64 times pi is approximately 201.06 (rounded to the nearest hundredth)
