Circumference of a circle = (pi) x diameter of the circle
therefore,pi = Circumference/diameter
or plot a graph of circumference against diameter using many circles and the slope of the line on the graph would be equal to pi.

What are 3 uses of pi?
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
How do find the value of pi?
To only three significant digits, pi is equal to 3.14. As for the method of finding pi, there are a few. Geometrically, pi can be obtained by finding the area of inscribed polygons with many sides. This can be written as an infinite series where the sides of the polygons increase unto infinity when it finally becomes the circle. In this case, the area of the circle with a radius of 1 is equal to pi. On the other hand, one can do the same thing with perimeters, then dividing the perimeter by the diamter. This will also give you pi. This was Archimedes' method, the previous was a method used by earlier mathematicians. In summation, the value of pi can be seen as the area of a circle with radius 1 or the ratio of the circumference to the diameter.
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
Why is pi important in layman term?
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
Method for finding solution to problems?
Experiments are a method for finding solutions to problems.

What is pi times the radius sq?
pi*radius2 is the formula for finding the area of a circle.
What is the formula for finding circumfernce?
circumference of a circle = 2*pi*radius or pi*diameter
What is pi used for in geometry?
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
What is the formula for finding the area of a cirlce?
