To find the radius of a circle when the circumference is given, you can use the formula for the circumference:
\[ C = 2\pi r \]
where:
- \(C\) is the circumference,
- \(r\) is the radius,
- \(\pi\) is approximately 3.14.
Given that the circumference \(C\) is 428 meters, we can rearrange the formula to solve for the radius \(r\):
\[ r = \frac{C}{2\pi} \]
Substituting the values:
\[ r = \frac{428}{2 \times 3.14} \]
Calculating the denominator:
\[ 2 \times 3.14 = 6.28 \]
Now substitute back into the formula:
\[ r = \frac{428}{6.28} \approx 68.15 \]
Thus, the radius of the circle, rounded to the nearest hundredths place, is:
\[ \boxed{68.15 \text{ meters}} \]
