Most pies are circular.
Okay, that was a cheap joke. The actual answer is that pi is the ratio of the diameter of a circle to its circumference. That means it shows up a lot in equations involving circles and circular things. It also shows up in a lot of places you might not initially expect. For example, the sum of the infinite series 4 - 4/3 + 4/5 - 4/7 +4/9 ... is Pi.

What is the difference between circle and Pi?
This is PI, pi = 3.14159265...... A circle is the round thing, like your pies! The area of a circle is measured using (Pi)(radius to the power of 2). Circumfrance of a circle is (Pi)(Diameter of circle).
What the formula in circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
What is the area of a circle with the side length of 12cm and a perimeter of 12cm?
A circle has no "sides". The "perimeter" of a circle is usually referred to as the circle's "circumference", i.e. the distance around it. The circumference of a circle is [ 2 pi R ], where 'R' is the distance from the center of the circle to its curve. If the circumference of a circle is 12, then 12 = [ 2 pi R ]. R = [ 12 / 2 pi ] = [ 6/pi ]. The area of a circle is [ pi R2 ]. If R = 6/pi, then the area is [ pi R2 ] = [ pi x (6/pi)2 ] = [ pi x 36 / pi2 ] = ( 36/pi ) = 11.459 square centimeters (rounded).
What does pi find?
Pi is the circumference of the circle divided by the diameter of the circle. Every circle, that ever was, is, or ever will be.
