To find the circumference of a circle, you can use the formula:
\[ C = 2\pi r \]
where \( C \) is the circumference, \( \pi \) is approximately 3.14, and \( r \) is the radius.
Given that the radius \( r \) is 63, you can substitute the values into the formula:
\[ C = 2 \times 3.14 \times 63 \]
Calculating that:
\[ C = 2 \times 3.14 \times 63 = 6.28 \times 63 \] \[ C = 395.64 \]
Therefore, the approximate circumference of the circle is 395.64.
