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 \(r = 8\) inches:
\[ C = 2 \times 3.14 \times 8 \] \[ C = 6.28 \times 8 \] \[ C = 50.24 \text{ inches} \]
So, the circumference of the circle is 50.24 inches.
The best answer from the options provided is:
B. 50.24in.
