are hard formulas including the pi sign
Pi is simply the ratio of a circumference of a circle to it's diameter. It is used in any calculation where you need to calculate angles and areas, and 3d space when combined with Sine and Cosine.
for instance the basic code
Xpos=offsetX+2pi(sin(x))
Ypos=offsetY+2Pi(cos(y))
Can be used to plot a circle in radians on a screen display when used in conjunction with a loop.
Yes. Some examples of formulas that contain pi (∏) are: (area of a circle) = ∏r2 (Circumfrance of a circle) = ∏d
Pi = circumference/diameter
Pi appears in calculations involving the circumference and the area of a circle; in problems involving the area and the volume of a sphere; in the volume of an ellipsoid; and in all sorts of problems that are not obviously related to circles and spheres.
Formulas relating to circles
All around the world, because pi is used in many formulas.
They are: 2*pi*radius or as diameter*pi
Area of a circle = pi*r2 Circumference of a circle = 2*pi*r or pi*d Volume of a sphere = 4/3*pi*r3 Surface area of a sphere = 4*pi*r2 Volume of a cone = 1/3*pi*r2*height Volume of a cylinder = pi*r2*height
3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.

The mathematical constant pi () is significant in engineering because it represents the ratio of a circle's circumference to its diameter. In the field of engineering, pi is used in calculations involving circles, curves, and waves. In the calculation of electromagnetic fields, pi is often used in formulas that describe the behavior of electromagnetic waves, such as in the equations for wave propagation and antenna design.
It's a number - used in problems involving geometry.
