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
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
It is not practical to work with the actual value of pi, because there is no actual value of pi. We all know that pi more or less equals 3.14159265 . . . but the number of decimal points in pi never ends. 3.14159 is extremely precise, and works for most uses.
