Pi is related to circles as it is used to measure the area, circumference, surface area and volumes of any 2-D or 3-D shape that has circles or circle-related surfaces.
In the case of area of a circle, it is measured as
pi x r x r, OR pi x r2 where r is the radius of the circle.
The relation between the radius and the circumference is also shown by by pi;
circumference / diameter ( or 2 x radius) = Pi
OR
circumference = pi x diameter
= 2 x pi x r
All related shapes like cones, cylinders, spheres, toruses, and even doughnuts can be measured using Pi.
Pi is usually given as 22/7, which doesn't even come that close. Another common value is 3.14, which is the cut off form of its value.

How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
What does pi in geometry mean?
Pi or π is a constant which represents the ratio of any circles's circumference to its diameter. which is always equal to 22/7 or 3.142any shape that has a curve in it (e.g circle) is related to pi....For example:1.area of a circle= πr22.perimeter of a circle= 2πr
What is circumference of a circle in terms of pi?
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
What is the relationship between a circles circumference and it's radius?
C=2(pi)r
What is the circles area if the diameter is 8?
Area of the circle = 16*pi square units
How is pie related to area of circles?
Area of any circle = pi*radius2
How can pi be used?
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
What mean of Pi related to circle?
Pi is the ratio of the circumference (the length going around the outside of the circle) to its diameter (the length going across the circle and through the center). Pi is constant for all circles.
Why does Pi work for all circles?
Because all circles are similar.
Where is pi found?
In circles in nature.
What is the answer to circles and circumference?
circumference = 2*pi*radius or pi*diameter
How to Calculate value of pi?
pi is an irrational number and cannot be expressed as a fraction. It is the ratio of a circles circumference to it's diameter...any circle...c/d See related link below
Why use pi?
Pi is very important for finding circumfrences and area's of circles.
What can you use pi for?
Formulas relating to circles
What do they use pi in?
To calculate properties of circles
Does Pi work for all circles?
Yes
How is pi used to find the circumference of circles?
Circumference of any circle = 2*pi*radius or pi*diameter
