Question

The radius is
cm.

The circumference in terms of π is
π cm.

Using 3.14 for π, the approximate circumference of the circle is
cm.

Answer 1

To calculate the circumference of a circle, you can use the formula:

\[
C = 2\pi r
\]

where \(C\) is the circumference and \(r\) is the radius.

Given the radius \(r\) in centimeters, the circumference in terms of \(\pi\) will be:

\[
C = 2\pi r \quad \text{(in terms of } \pi\text{)}
\]

To find the approximate circumference using \(3.14\) for \(\pi\), you would calculate:

\[
C \approx 2 \times 3.14 \times r
\]

Let's say your radius \(r\) is a specific measurement, you can substitute it into the formulas above.

### Example:
If \(r = 5\) cm:
- Circumference in terms of \(\pi\) would be:
\[
C = 2\pi \times 5 = 10\pi \text{ cm}
\]
- Approximate circumference using \(3.14\):
\[
C \approx 2 \times 3.14 \times 5 = 31.4 \text{ cm}
\]

Please provide the radius in centimeters so that I can give you the specific values!
