Answer:

25.1

Step-by-step explanation:

The formula to find the circumfrence of a circle is C=2πr. Where r represents the radius. We have to find the radius first. The diameter is 8, and we know the diameter is 2 times the radius so our radius is 4. If we plug in the numbers we have, we get the equation C=2*(3.14)*4. Solve for C and you end up with 25.12, rounded to the nearest tenth and you have 25.1.
