Answer:
B. 66.0
Explanation:
One of the radius measure 10.5 because the line is between the center point and the edge of the circle.
Circumference = 2πr
C = 2(3.14)(10.5)
C = 2(32.97)
C = 65.94 ≈ 66.0
Circumference of a Circle Formula: C = 2πr
We are given r = 10.5, so simply plug it in:
C = 2π(10.5)
C = 21π
C = 65.9734
or
C ≈ 66
