Area of a circle = (pi) x (radius)2
Radius = 1/2 the diameter = 5 inches
Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
Circumference = pi D = 10 pi inchesEach side of the square = (10 pi) / 4 = 2.5 pi = 7.854 inches (rounded)or 7.9 inches, to the nearest 1/10th inch
Conversion of arc seconds to inches depends on the distance that is being measured. There are 360 degrees in a circle, 60 minutes per degree and 60 seconds per minute. The circumference of a circle is PI * diameter. So 1 arc second of a 1 foot diameter circle is equal to .000029 inches. (12 * PI inches diameter divided by (360*60*60))

25 square inches.
it would be the diameter of the smaller circle times sqrt 2
28.00563 inches, roughly equal to 28 inches
The largest diameter you can inscribe in a circle is a square. The square's diagonal is equal to the diameter of the circle; the length of the side of the square is therefore equal to the circle's diameter, divided by the square root of 2.
A circle with a diameter of 12 inches has an area of 113.1 square inches.A circle has an area equal to its radius squared times pi. Your circle has a radius of 6 inches (half the diameter)6 X 6 X 3.14159...=113.097336
16 inches
The radius of a circle with an area equal to 225.97 square inches is: 8.481 inches.
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
The diameter of the circle is 11.997 units.
The diameter of the circle is equal to the diagonal of the square, or the (side of the square) times the (square root of 2).
It is: 2*radius = square root of (616/pi) = 28 inches to the nearest integer
The circle's area is 176.71 square feet.
A circle with a diameter of 156 feet has an area of 19113 square feet (approx).
16x16 inch tiles are square. If you place them on a circle, the edges will hang off, so we first need to find the size of the largest square that will fit in the circle. The largest square can be made of four isosceles triangles whose equal sides are equal to the length of the radius, so the area of the contained square is 2r2. An 11-foot diameter circle has a radius of 5.5 feet, so the square has an area of 2(5.5)2 = 60.5 square feet, or 60.5 * 122 square inches = 8712 square inches. The 16x16 tiles are 256 square inches, so 8712 / 256 = 34.03125 tiles that fit completely in the circle.
