Answer:
B. Circle B
Explanation:
The radius of a circle is the center point of a circle to the outer side of the circle. The diameter of a circle is from one side of the circle to the other in a straight line. We can multiply the radius of circle B by 2 to get the diameter of circle B. The diameter of circle B is 10 and the diameter of circle A is 9, so the larger circle/circumference would be circle B.
