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 of the circle.
Given that the radius \( r \) is 10:
\[
C = 2\pi \times 10 = 20\pi
\]
If you want a numerical approximation, you can use \( \pi \approx 3.14 \):
\[
C \approx 20 \times 3.14 = 62.8
\]
Thus, the circumference of the circle is \( 20\pi \) or approximately 62.8 units.
