If the circumference of the 841.52, what is the radius of the circle?

To find the radius of a circle when the circumference is known, you can use the formula for circumference:

\[
C = 2\pi r
\]

where:
- \( C \) is the circumference,
- \( r \) is the radius,
- \( \pi \) is approximately 3.14159.

Given:
- \( C = 841.52 \) units,

You can rearrange the formula to solve for the radius \( r \):

\[
r = \frac{C}{2\pi}
\]

Substituting the values:

\[
r = \frac{841.52}{2 \times 3.14159} \approx \frac{841.52}{6.28318} \approx 134 \text{ units}
\]

So, the radius of the circle is approximately **134 units**.
