Given:
• Circumference of the circular field, C = 248.06 yards
,
• π = 3.14
Let's find the diameter of the field.
To find the diameter of the field, apply the formula:

Where C is the circumference and d is the diameter.
Rewrite the formula for d:

Substitute values into the equation and solve for d:

Therefore, the diameter of the circular field is 79 yards.
ANSWER:
79 yards
