Divide the diameter by 2 to get the radius. Then use the formula:
area = pi x radius2.
circomference of a circle = pi*diameter = pi*14
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
54 in = 4.5 ft
4.5 feet are in 54 inches
4.5 feet are in 54 inches
54 feet
4.5
3.5 ft
18 yards.
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
6in * 54 ft * 24 ft = 0.5 ft * 54 ft * 24 ft = 648 cubic feet.
Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.
