there is no equation of Pi
Circumference divided by diameter
I think it is 3.14 that equals to pi when u solve it
The formula is pi x the diameter of the circle, which is also pi x (2 x the radius) C = pi * D C = pi * 2r
4 pi r 2
first the parametric equation of a sphere is X=cos(a) Y= sin(a)*cos(b) Z=sin(a)*sin(b) the equation of a cube is of the same type except that you have to multiply X,Y,and Z by A=(1+tan(a-pi/2*(floor((a+pi/4)/(pi/2))))²)^(1/2) and Y and Z by B=(1+tan(b-pi/2*(floor((b+pi/4)/(pi/2))))²)^(1/2) And the result should be a cube Ps: remove Z and take b=0 and you should have the equation of a 2D square, if you want explanations i can give you some but it's a bit long...
I think you want formula's for a Cylinder? Volume = (pi)r^2 x height Surface Area = 2(pi) radius x height
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
I think it is 3.14 that equals to pi when u solve it
perimeter = pi * diameter, or 2 * pi * radius
circumference of a circle = 2*pi*radius or diameter*pi
Pi, or 3.14159... Using the equation Circumference = pi * diameter.
pi = c/d Whereas c is the circumference of a circle and d is its diameter.
PR= (Pi-Pt)2/(Pi+Pt)2 x 100
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
in terms of pi- when using the symbol for pi instead of 3.14 or 22/7 in the end result of an equation
