HELP ASAP! Draw AB and construct its perpendicular bisector. Identify point C on the bisector. Measure the distance from point C to point A and from point C to point B. What theorem does your measurement justify? Explain your answer.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
