If your measurement of 4.5 feet is the diameter of the circle, then the circumference equals 4.5 times pi. Pi is a never ending number, but with only 3 or 4 decimal places, you can get pretty accurate answers. Pi is approximately equal to the number 3.14159265. In this case, 4.5 x Pi = 14.1372, more or less, and that is the size of the circle's circumference.
Area of a circle = pi*radius2 measured in square feet
A 45-foot circumference circle has an area of: 161.1 square feet.
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
The description, a 6 foot circle, would normally be understood to mean a circle with a diameter of 6 feet. Circles are most usually measured by their diameter.
100 ft * 45 ft = 4500 sq ft.100 ft * 45 ft = 4500 sq ft.100 ft * 45 ft = 4500 sq ft.100 ft * 45 ft = 4500 sq ft.
Area of circle = Pi x diameter2/4 = 3.142 x 49/4 = 38.49 sq ft
The 2011 Lincoln MKT's turning circle is 40.7 ft..
There are no 45 ft containers
If the circle is 20 ft radius, the area is π·20² = 1256.637 ft² If the circle is 20 ft diameter, the area is π·(20/2)² = 314.1593 ft² If the circle is 20 ft circumference, the are is π·(20/2π)² = 63.66198 ft²
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
The circumference of a 30 ft circle is: 94.2 feet.
The circumference of an 8 ft circle is: 25.1 feet.
