It is used to work out the area of a circle by using the formula πr2 and the circumference (Perimeter) πd.
πr2 - Area: Pi x Radius2
πd - Circumference: Pi x Diameter
π = 3.1415...
The circumference of a circle divided by its diameter is equal to the value of pi.
Pi is the circumference of a circle divided by the diameter of a circle. 3.14 is an approximation of Pi. It is not possible to display the value of Pi. (See the related questions.)
So soccer has the circle in the middle of the field. That is related to pi because it is a circle. That is how they are related!
The value of pi in a circle is: circumference/diameter
Pi is related to the diameter of a circle through the circumference. C=(pi)*d C = circumference (perimeter of the circle) pi = constant d = diameter
You get the value of pi by dividing the circumference with the diameter of a circle. pi = c/d
The value of pi = circumference/diameter
3.1416
Pi is related to the area of a circle because it just is. It is closely related to it in math, and to find the circumference (PI 3.14), you must know the area or the diameter.
The circumference of a circle divided by its diameter is equal to the value of pi.
Ratio of the perimeter of a circle (circumference) to its diameter
The area of a circle is its diameter times the value of PI. In most cases you can safely use the 3.14159 for the value of PI
