What is the relationship between the radius of a circle and its area?
area = pi*r2 where pi is the irrational number approximated by 3.14159
What is the relationship between the area of a circle and its radius squared?
The area of a circle is defined by the equation A = πr^2 where π = pi (3.14...) A = Area r^2 = radius squared So, the radius of a circle squared multiplied by pi equals the area.
What is the relationship between pi and radius?
Pi and the radius can be used to find the area (PiR^2) or the circumference (2RPi) of a circle, where R is the radius.
Why pi is used to find area and volume?
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.
What is the definition of pi?
Pi is defined as the circumference of a circle divided by its diameter. This relationship carries a value of approximately 3.14159 as a constant. Additionally, Pi is defined also by a circle's area divided by its radius squared.

What is the relationship between the circumference of a circle and the area of a circle?
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
What is the relationship between the area and the radius?
In relation to the area of a circle: pi*radius^2

What is relationship between the area of a circle and a rectangle?
area of a circle = area of a rectangle(parallelogram) formed by the sectors of circle with pi as length and radius as bradth.

An architect determined the relationship between V the volume of a sphere and S the surface area of the sphere. Write a equation that represents this relationship?
Volume of a sphere = 4/3*pi*radius3 measured in cubic units Surface area of a sphere = 4*pi*radius2 measured in square units
How do you calculate circumference and area of pi?
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
What is Pi and who invented or discovered Pi?
Pi is the relationship between the diameter and the circumference of a circle.
Why is pie used to calculate properties of a circle?
The simple answer is that PI is what falls out when you study circles. If I had a circle that is 1 foot in diameter, then the circumference (or perimeter) is PI feet. The numerical value of PI wasn't chosen at random, it was found. As for the area of a circle, the perimeter of any object has a relationship to its area. So, PI again becomes important.
