Inner radius of walk = R1 = 10/2 ft = 5 ft.

Outer radius of walk = R2 = 5ft + 3 ft = 8 ft

Area of fountain = pi*R12 = 78.54 sq ft

Area of fountain + walk = pi*R22 = 201.06 sq ft

So area of path = 201.06 sq ft - 78.54 sq ft = 122.52 sq ft.

What do circles have to do with science?

Circles were invented around 2000 years ago by the Indian astronomer Sai Bakrushkuphen during a challenge hosted by King Chandragupta to see who could come up with the best shape to describe the sun. As a result of Bakrushkuphen's discovery, people no longer had to describe objects like the sun, the moon, and wheels with vague terms like "smoothed over square", and instead could just use one simple word: "circle". Bakrushkuphen's discovery not only had important implications for his age, but also paved the way for future scientific discoveries, such as the trapezoid, the hexagon, and the rhombus and it played a vital role in the development of the third dimension.
