Answer:


C = 25.1 \text{ cm}

Explanation:

We can find the circumference of the circle by plugging the given radius value 8 cm into the formula:


C = \pi d

Note: This formula can also be written as
C = 2\pi r because
2r = d.

↓ plugging in the given radius


C = 8\pi \text{ cm}

↓ rounding to the nearest tenth


\boxed{C = 25.1 \text{ cm}}
