A soccer scholar wants to take a string from the center of the soccer field to the edge of a circle on the field. If the circumference of the center of the field is 10 feet away, how many feet of the string will the scholar need?

In this scenario, the scholar is looking to measure the distance from the center of the soccer field to the edge of a circle on the field. This distance corresponds to the **radius** of the circle.

Given that the **circumference** of the circle is 10 feet away, we can use the formula for the circumference of a circle to find the radius. The formula for circumference is:

\[
C = 2 \pi r
\]

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

Since the circumference \(C = 10\) feet, we can solve for \(r\):

\[
10 = 2 \pi r
\]

\[
r = \frac{10}{2 \pi}
\]

\[
r \approx \frac{10}{6.2832} \approx 1.59 \, \text{feet}
\]

Thus, the scholar will need approximately **1.59 feet** of string to reach from the center of the field to the edge of the circle.

Would you like further clarification on the math behind this? Or would you like to explore more related questions?

Here are some related questions you may find interesting:
1. How would the radius change if the circumference were 20 feet?
2. What would be the area of the circle if the radius is 1.59 feet?
3. If the scholar used 2 feet of string, what would happen in terms of the circle's size?
4. How is the diameter of the circle related to the radius?
5. How do you calculate the circumference of a circle if you know the radius?

**Tip**: Always remember that the circumference is directly proportional to the radius; if the radius doubles, the circumference will also double!

A detailed solution for calculating the radius of a circle when the circumference is known. In this example, the circumference is 10 feet, and using the formula C = 2πr, the radius is calculated to be approximately 1.59 feet. Suitable for students in Grades 6-8.
