Circumference = pi x the diameter / pi x twice the radius / pi x square root of "area divided by pi".
C = (pi) D
C = 2 (pi) r
C = 2 (pi) * [sq rt (A/pi)]
r = radius
D = diameter
pi = 22/7 or 3.14

What meaning of PI TERMS OF PAY?
Pi is the number you get after finding the ratio of a circle's radius to its circumference. It's used in formulas to find the circumference and area of circles. The number goes on infinitely, but most people abbreviate the decimal to 3.14.
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 does pi mean?
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
Why is it important to know the difference between diameter and radius?
When you are using mathematical formulas, it is good to know the difference. For example finding the circumference or area of a circle.
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
What is the circumference of a circle with a diameter of 1.5 meters?
The formula for finding the circumference of a circle is:-circumference of a circle = pi * the diameter of circlewhere The value of pi is approximately 3.14thus the circumference = 3.14*1.5 = 4.71 meters
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
What are the formulas to find the circumference in a circle?
C=Pi*D
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
Where and when can you use a pi in maths?
Finding are or circumference of a circle or cylinder.
What number is useful when finding the circumference of a circle?
The value of Pi
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
