Pi (π) is intertwined with the circle in all sorts of ways. First of all, it is the ratio of a circle's circumference compared to its diameter. Meaning, if a circle has a diameter of 1 m, its circumference is π m, or roughly 3.14 m.
You also use π to find the area of a circle, the formula being πr2
You can get into more complicated uses of π and circles in calculus and physics, but it all relates back to its ratio constant for circumference.

Is Pi 3.14?
Pi is the circumference of a circle divided by the diameter of a circle. 3.14 is an approximation of Pi. It is not possible to display the value of Pi. (See the related questions.)
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the circumference of 23cm circle?
circumference of a circle = 2*pi*radius or pi*diameter
What happens to the area of a circle when the radius is tripled?
The area of the circle becomes 9 times the area of the original circle. Original circle = Pi * (r ^ 2) = Pi * r * r New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
How is pi and soccer related?
So soccer has the circle in the middle of the field. That is related to pi because it is a circle. That is how they are related!
How is pi related to the diameter of a circle?
Pi is related to the diameter of a circle through the circumference. C=(pi)*d C = circumference (perimeter of the circle) pi = constant d = diameter
How are the circumference of a circle the diameter of a circle and pi related?
The circumference of a circle divided by its diameter is equal to the value of pi.
How is Pi related to the area of a circle?
Pi is related to the area of a circle because it just is. It is closely related to it in math, and to find the circumference (PI 3.14), you must know the area or the diameter.
Pi is a mathematical constant related to circle define Pi?
Ratio of the perimeter of a circle (circumference) to its diameter
How is pi and area related?
area of a circle pi *r^2
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
Is Pi 3.14?
Pi is the circumference of a circle divided by the diameter of a circle. 3.14 is an approximation of Pi. It is not possible to display the value of Pi. (See the related questions.)
What mean of Pi related to circle?
Pi is the ratio of the circumference (the length going around the outside of the circle) to its diameter (the length going across the circle and through the center). Pi is constant for all circles.
How is pi related to the circumference area of a circle?
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
How is pie related to area of circles?
Area of any circle = pi*radius2
How is the perimeter and area of a circle related?
They both use pi to determine their values
