To find the area of a circle, you can use the formula , where is the radius. Since the diameter is 28 yards, the radius is half of that: yards. Now plug the radius into the formula:

square yards.

So, the area of the circle is approximately 615.44 square yards.

Did you know that circles have fascinated humans for thousands of years? Ancient civilizations, including the Egyptians and Greeks, studied circular shapes for everything from architecture to astronomy. Archimedes was one of the first to calculate the area of a circle, and even today, his work still influences everything from engineering to design!

In practical terms, understanding how to calculate areas of circles is essential in various fields. For example, landscapers need to know how much sod to order for a circular garden, while engineers use these calculations when designing round components like gears and wheels. Knowing that little formula can come in handy in surprising ways!
