A circle with a diameter of 9 feet has a perimeter of 28.3 feet.
The formula for the area of a circle is pi (3.141265...) times the radius squared. Since half of the diameter is the radius, plug that number into the formula to get the total square feet.
If you are talking about around the circle (Circumference) then the are about 3.14 diameters and 6.28 radii While if you are talking about just across, the 1 diameter and 2 radii. Hope this Helps ;) Please recommend me :)
Sure. Any chord that passes through the center of the circle is also a diameter. Chords can have many different lengths, but a diameter is the longest chord.
A 48-inch diameter circle has an area of: 12.57 square feet.
