Circumference of a circle: 2*pi*radius or diameter*pi
Area of a circle: pi*radius squared
615.75
28 x 3.1416: circumference is pi times the diameter.
area of a circle = pi time r2 A diameter of 28 feet means a radius of 14 feet area = pi times 196 or 615.75 square feet
The circumference is 175.92918860102841 feet.
If the diameter is 18 feet then the area is about 254.469 ft². If the radius is 18 feet then the area is about 1017.876 ft².
The area of a 28-foot diameter circle is: 615.752 feet2If the circumference is 28 feet then the area is 62.388 feet2
Area of the circle in square feet = pi*radius2
8.5344 metres per 28 feet.
28 feet is 336 inches. (12 inches per foot),
28*15 = 420 sq ft
476 square feet (28 x 17 = 476).
There are 0.3048 metres in one foot. Therefore, 28 feet is equal to 28 x 0.3048 = 8.5344 metres.
