circumference of a circle = 2*pi*radius or diameter*pi

the number is that you use for pi is 3.14 the number is that you use for pi is 3.14

If you draw a circle and then create a square around it so all four sides touch, pi is the number that represents the ratio of the sizes of the two shapes.

Pi is the number you have to use to solve many circle equations. If you want to find the area of a circle, use radius squared times pi. For the circumference, use diameter times pi.

No. For example 1 sq. f. circle has 2*Pi*(1/Pi)^0.5 perimeter and 1 sq. f. square has perimeter of 4. As you can see 2*Pi*(1/Pi)^0.5 does not equals 4.

Pi is the ratio between the circumference of a circle and its diameter. The first and most obvious way to find pi is to measure both the circumference and the diameter. This gives a very rough approximation. A second way is to use geometry. By fitting regular shapes with large numbers of sides both around and inside the circle we can narrow the boundary for the potential value of pi. The most accurate way to find pi is to do with its use in certain very complex formulae. Computers are required to determine pi to an infinite decimal place.

Just divide 56 by pi. Pi is approximate 3.14; or use the "pi" key on your scientific calculator.Just divide 56 by pi.
