circumference is the distance around the circle, so it sounds as though you are stating the circumference in your original question; 66 inches.
66 = 198
66 squared equals 4,356.
If 150 / x = 66, then x = 2.2727 cmSuppose the length is L cm.Then 150*L cm = 66 cmSo L cm = 66 cm/150 = 66/150 cm = 0.44 cm = 4.4 mm.

A circle with a diameter of 66 feet has an area of 3,421.19 square feet.
5.50 feet (66 inches divided by 12 inches in a foot)
The Antarctic Circle is about 66 degrees S.
