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).

Why is pi used in every circle formula?
By definition Pi is the relation between the radius and circumference of a circle.
Is the radius of a circle divided by the circumference of a circle pi?
No, the circumference of the circle divided by the diameter is pi.
What is the formual for pi?
the formula for pi is the ratio of the circumference of a circle to the diameter of the circle
Why is the unit circle called two pi?
A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.
If the area of one circle is four times as large as a smaller circle with radius of 3 inchesThe radius of the larger circle is?
6 inches pi*32 = 9*pi square inches (smaller circle) pi*62 = 36*pi square inches (larger circle)
What is the relation between circle and pi?
The circumference of a circle divided by its diameter is equal to the value of pi.
Why is pi used in every circle formula?
By definition Pi is the relation between the radius and circumference of a circle.
Relation of pie With circle?
The value of pi for any circle is the circle's circumference divided by its diameter.
What is the relation between pi and circle mathematically?
A circle's circumference when divided by its diameter is the value of pi which is an irrational number because it can't be exactly expressed as a fraction.
What is the relationship between the area and the radius?
In relation to the area of a circle: pi*radius^2
What is the circumference of an 10.5 inch circle?
Circumference of a circle = 2*pi*radius or pi*diameter
What is pi and how does it relate to the circumfrance?
The number pi is the ratio of the circumference and the diameter of a circle. In Euclidian ("flat") geometry, this ratio is the same for all circles. The number pi is approximately 3.1416. It also has many other uses in mathematics and physics, not all of which have an obvious relation to a circle or sphere.
What is relation between pie and circle?
It is pi, a letter in the Greek alphabet, and pronounced like pie. This infinite value, usually expressed as 3.14 or sometimes more accurately as 3.1416 is the ratio of the diameter (distance across) a circle, and the circumference (distance around) a circle. The diameter times pi equals the circumference, and the circumference divided by pi gives the diameter. Also, the radius (half the diameter) times itself and then multiplied by pi gives the area inside a circle. The value of pi is the same regardless of the size of a circle.
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 is the circumfrence of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
What is the mathemathical formula of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
What the formula in circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
