The diameter of a circle can be divided into the circumference of a circle pi times. The number pi is about 3.14 in decimal form. Because pi is an irrational number, it cannot be written as a fraction of integers or as a terminal or repeating decimal. The circumference of a circle is said to be pi times the diameter, so by dividing the diameter into the circumference, we would get pi as a quotient.
"Leaving pi as pi" means not simplifying or approximating the mathematical constant pi (π) in calculations or expressions. It is often done to maintain accuracy and precision in mathematical computations, especially when working with trigonometric functions or geometry. By leaving pi as pi, you ensure that the value is exact and not rounded off, which can be important in certain mathematical contexts.
