if circle A has a radius of 6 millimeters, with a circumference of approximately 38 millimeters, and circle B has a radius of 60 millimeters, then what is circles B's approximate circumference

Answer 1

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.
