Solution
Solution Steps
Step 1: Formula
The formula for the circumference of a circle is $C = \pi d$, where $C$ is the circumference and $d$ is the diameter.
Step 2: Substitute and solve for d
Given $C = 25.12$ yards and $\pi \approx 3.14$, we can substitute these values into the formula:
$25.12 = 3.14d$
To solve for $d$, divide both sides of the equation by 3.14:
$d = \frac{25.12}{3.14}$
$d = 8$
