The area of a circle is pi times the square of the radius. Pi has no relationship with the area of a polygon.
pi
pi is approximately 3.14, and is the ratio of any circle's diameter to its circumference.
Circumference of a circle is 2 x Pi x the radius
diameter times pi(3.14159) equals cicumference
circumference of of circle / Radius of the circle
The area of a circle is pi times the square of the radius. Pi has no relationship with the area of a polygon.
pi X diameter = circumference of the circle.
Pi is the relationship between the diameter and the circumference of a circle.
pi
pi is approximately 3.14, and is the ratio of any circle's diameter to its circumference.
Circumference of a circle is 2 x Pi x the radius
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
The circumference and diameter
diameter times pi(3.14159) equals cicumference
Pi ( 3.142 approx.) is the amount of times the diameter of a circle can be measured along the circumference of a circle. We know that Pi multiplied by the diameter of the circle is equal to it circumference. So we write C=PiD This means, as it says above, that a certain number of "Pi's" will be equal to the circumference.
The circumference of a circle is equal to pi times its diameter. Another way to say this is that for any circle, circumference divided by diameter will always have pi as the answer, regardless of the size of the circle.
