To find the circumference of a circle, you can use the formula:
\[
C = 2 \pi r
\]
where \(C\) is the circumference and \(r\) is the radius.
For circle B, with a radius of 60 millimeters, the circumference is calculated as follows:
\[
C = 2 \pi (60)
\]
\[
C \approx 2 \times 3.14 \times 60
\]
\[
C \approx 6.28 \times 60
\]
\[
C \approx 376.8 \text{ millimeters}
\]
So, the approximate circumference of circle B is **about 376.8 millimeters**.
