Diameter = 12.5 ft => radius = 12.5/2 = 6.25 ft.
Then area = pi*r2 = 122.72 sq ft, approx.

A 15-foot wide circle has an interior area of 176.71 square feet and a distance around the outside (circumference) of 47.1 feet.
The answer depends on what the 54 feet measures: the radius, diameter or circumference.
726 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
If a circle is 50 feet wide, that means its diameter is 50 feet. The radius of a circle is half the diameter, therefore the answer is 25 feet.
855 square feet.
