3.14159265 That Pi?
Many people use Pi.
I use Pi in my math class.
Math teachers, Engineers, and students taking trigonometry and geometry.
You need Pi to find the radius or circumference of a circle and there are many more uses!

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 Ball uses pi and so does the half circle near the goal and the center circle
a formula that uses pi is the circumference and area of a circle and every polyhedron that has a circle
its phps becoz n-pi* excitation requires less energy than pi-pi*
the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade
In the story "Life of Pi" by Yann Martel, Pi kills a flying fish by hitting it with an oar. He then uses the fish as bait to catch a dorado.
For almost all mathmatics and physics uses, pi is writen as 3.1417. But it is actually an irrational number, and has no perfect answer.
For the vast majority of day-to-day uses, pi is quoted as 3.14. This is equivalent to 3 significant figures, 2 decimal places, or pi 'to the nearest hundreth'.
think of things that are round, for example, findind the circumference of a pool or a cup
Some of its uses and applications are as follows:- Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius2 Volume of a sphere: 4/3*pi*radius3 Surface area of a sphere: 4*pi*radius2 Volume of a cone: 1/3*pi*radius2*height Curved surface area of a cone: pi*radius*slant length Volume of a cylinder: pi*radius2*height Entire surface area of a cylinder: (2*pi*radius2)+(diameter*pi*height) Pi is the value of a circle's circumference divided by its diameter Pi is the 16th letter of the Greek alpabet
