Because the ratio of the circumference of any circle to its diameter is pi.
Because the ratio of the circumference of any circle to its diameter is pi.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
It is used to find the area of a circle as pi*radius2
Area of a circle equals pi (3.14) times the radius squared.
Angular measure of a circle: 2*pi radians. Circumference of a circle with diameter d units: d*pi units
Any circle will work!
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
By definition Pi is the relation between the radius and circumference of a circle.
Pi is used to find area and circumference of a circle.
It is used to find the area of a circle as pi*radius2
Pi can be used to find a circle, For the circumference-Pi x D, or for the radius Pi x r2
It is a Greek letter used to represent the ratio of the diameter of a circle to its circumference so you can see 'pi' (not a pi)in any circle.
Area of a circle equals pi (3.14) times the radius squared.
To find out the area of a circle.
Pi is used in nearly every branch of math. If you need to do anything with a circle, pi was used to make that circle. Any measurement of a circle, cylinder, sphere, etc involves pi. Pi is incorporated into the GPS. All kinds of things use pi. A fun fact for pi: the actual length of a river compared to the straight distance from source to mouth will yield pi.
well pi is used to find the area of a circle A=pi x the radius squared
The circumference of a circle can be calculated by multiplying pi by the diameter of the circle. For example if the diameter is 10 then the calculation will be pi x 10 = answer. The most commonly used value for pi is 3.14
Pi is used in many ways today. The simplest way it to find the circumference (the perimeter) of a circle or the area (amount of space inside) of a circle.
