Answer:
Circle B has a larger circumference.
Step-by-step explanation:
Circumference of a circle is the diameter times pi.
C = pi•d
Circle B has radius 5, so its diameter is 10. Circle A has diameter of 9. A larger diameter will give a larger circumference.
C_circle A = 9pi
~= 28
While,
C_circle B = 10pi
~= 31
Circle B's circumference is about 3 cm larger. More accurately it's 1pi larger.
