Pi can be used to calculate the circumference of a circle
Any circle will work!
π r 2 (pi times the radius squared)
Circumference of a circle = 2*pi*radius or pi*diameter
To calculate the area of a circle use this formula: pi x r2.
Pi (π) is calculated as the ratio of a circle's circumference to its diameter. Therefore, the two numbers used to calculate pi are the circumference of the circle and its diameter. This relationship holds true for all circles, making pi a constant approximately equal to 3.14159.

pi is an irrational number at 3.141592.... ( recur to infinity and decimals in no regular order. Let me tell you a story!!!! It was found by the 'Ancient Civilisations' that when a donkey is used to drive up water from well, it was tethered to a rope/halter, the radius. It walked round the well head tied to the halter. in a big circle, the circumference. It was found by the ancients, that twice the radius, the diamter, has a direct proportion to the circumference. It didn't how big/small the circumference was, compared to the radius/diameter the proportion always remained the same at 3.141592.... (pi). So the ancints constructed an equation. C is directly proportional to diameter ,d, This proportion is always constant hence a 'k' for constancy is inserted. C = kd or k = C/d This constant 'k' was given the name 'pi', which is the lower case Classical Greek letter 'p'. and stands for proportion. So ther you have it!!!!!
Circumference of a circle = 2*pi*radius or pi*diameter
The perimeter or circumference of a circle = 2*pi*radius or pi*diameter

you use pi to calculate the area or circumference of a circle
We can calculate the area of a circle by using the formula areacircle pi times r2. We know that pi is about 3.14 and r is the radius of the circle. Πr2 Where: Π pi (3.14159265...) r radius of circle
No, pi is a ratio, often simplified as 22/7, used to calculate areas of circles, etc.So, the area of a circle is pi times r2, where r = the radius of the circle.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.
