pi (3.1416, etc) (or 22/7) is the fundemental constant (given or a priori) in the relationship between the area of a circle and its radius or diameter).
i.e. area of a circle =Pi X R squared.
Likewise the circumference is Pi X D where D is the diameter of the circle.

How do you find the diameter and volume of a sphere if you have the surface area?
4*pi*radius2 = area radius = square root of (area/4*pi) diameter = 2*radius volume = 4/3*pi*radius3
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
How can pi help you measure?
Pi is not a size. Pi is usually 22/7. Sometimes also 3,14. Pi is used to measure area and circumference of a circle, and the volume of sphere / tube. If there is no pi, then the area and circumference of circle, and the volume of sphere / tube will not be counted.
How is pi r squared used?
It is used to find the area of a circle as pi*radius2
What is pi used for in geometry?
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
What 3 things in math is pi used to find?
Pi is used to find the area and perimeter of a circle and the volume of a sphere, cylinder, and cone. Pi=3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196... That was 200 decimal places of Pi.
Why is the volume pi r h for a cylinder?
pi r^2 h is used to determine the volume of a cylinder because when determing the area of a shape you first have to determine the area of the the base of the object and then multiply it by the height. The base of a cylinder is a circle and to find the area of a circle you use pi r^2 and hence the reason why pi r^2 is used to find the volume of the cylinder.
How do you find the diameter and volume of a sphere if you have the surface area?
4*pi*radius2 = area radius = square root of (area/4*pi) diameter = 2*radius volume = 4/3*pi*radius3
Why do you use pi to find volume?
You use pi to find volumes that include circles, as volume = area x depth, and the area of a circle always involves pi
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3

Where is pi used?
Pi can be used to solve many different things, such as the circumference, radius, diameter, or area of a circle, and the volume of a sphere.
When is pi typically used in mathematics?
Pi is used to find area and circumference of a circle.
How is pi r squared used?
It is used to find the area of a circle as pi*radius2
How do you find the volume of circle?
With great difficulty because a circle does not have volume but it does have an area. Area of a circle = pi*radius2 and measured in square units
How have you used pi?
To find out the area of a circle.
