Explain pi as easy as possible

Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. In simple terms, it tells us how many times the diameter of a circle can fit into its circumference. It is approximately equal to 3.14159, but it goes on forever without repeating. Pi is used in many areas of math and science to calculate and understand properties of circles and other curved shapes.

give me an example

Sure! Let's say we have a circle with a diameter of 1 inch. If we want to find the circumference of this circle, we can use pi.

Using the formula for circumference, which is C = πd, we can substitute the diameter into the equation.

So, C = π * 1 inch.

Since π is approximately 3.14159, we can calculate the circumference as follows:

C = 3.14159 * 1 inch.

Therefore, the circumference of the circle is approximately 3.14159 inches.
