Pi is equal to 3.14, for the area of a circle, is 3.14 x r x r. (r=radius)
Pi is the ratio of the diameter of a circle to the circumference of a circle.
It is an irrational number but can be taken to equal 3.14 in most circumstances.
That is, the circumference is 3.14 (approx) times greater than the diameter. So if you know one you can calculate the other.

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.
