there is no equation of Pi
Circumference divided by diameter
If: circumference = pi*diameter Then: pi = circumference/diameter
22/7=pi (roughly) 7 times pi is 21.99115 pi is 3.1415926535898 etc
"Pi" is not an equation - it is a constant. Pi is irrational, that is, it cannot be expressed as a ratio of constants, but it can be truncated for common use (approximately 3.1415). Pi is given by the circumference of a circle divided by the circle's diameter: Pi = C / d
Pi x twice the radius or pi times the diameter
perimeter = pi * diameter, or 2 * pi * radius
I think it is 3.14 that equals to pi when u solve it
circumference of a circle = 2*pi*radius or diameter*pi
Pi, or 3.14159... Using the equation Circumference = pi * diameter.
Pi x (radius of circle)2 Pi=3.146
the radius squared x pi
the circumference of a circle divided by its diameter
Circumference = Pi x Diameter (Pi equals 3.14)
