Solution

1. Break Down the Problem

To find the radius of the circular field, we can use the formula for the circumference of a circle:

C=2πr C = 2\pi r

where C C is the circumference and r r is the radius.

2. Relevant Concepts

We know the circumference C=204.1 C = 204.1 yards and π3.14 \pi \approx 3.14 . We need to solve for r r .

3. Analysis and Detail

Rearranging the formula to solve for r r :

r=C2π r = \frac{C}{2\pi}

Substituting the known values:

r=204.12×3.14 r = \frac{204.1}{2 \times 3.14}

Calculating the denominator:

2×3.14=6.28 2 \times 3.14 = 6.28

Now, substituting this back into the formula:

r=204.16.28 r = \frac{204.1}{6.28}

Performing the division:

r32.5 r \approx 32.5

4. Verify and Summarize

We calculated r r as approximately 32.5 32.5 yards. The derived steps confirm that the radius is correct given the circumference.

Final Answer

The radius of the field is 32.5 32.5 yards.
