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
angle of the circle/360 x 2(pi)r
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).
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
When you are using mathematical formulas, it is good to know the difference. For example finding the circumference or area of a circle.
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
