Stonehenge, an ancient monument in England, may have been used as a calendar. The stones are arranged in a circle 30 meters in diameter. Find the area of the circle.
The area of a circle is Pi times the diameter. So depending on what Pi equals in this problem it could be one of two answers If Pi is not a number it's just 30 Pi If the number is 3.14 then the number is 94.2 Hope this helps
