Due to the commutative law of multiplication, order is not a factor. The formula is simply Pi times the radius of the circle squared, or multiplied by itself. TT x r x r, or r x TT x r. (Where TT=Pi, or 3.14159...)
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Area of circle = pi*(radius)2
It's important to estimate before finding the real answer for any numerical problem in arithmetic or any other kind of math, so that when you think you have the real answer, you can immediately recognize whether it's total baloney or has a chance of being correct.
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Area of a circle = pi*radius2
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
When you are using mathematical formulas, it is good to know the difference. For example finding the circumference or area of a circle.
Area of a circle = pi*radius squared
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
Pi * R squared, where R is the radius of the circle in question
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Area of circle = pi*(radius)2
