First of all it is NOT 'pie', that is the meat pie or apple pie that you eat. The circular 'pi' is 'pi' (small/lower case) . 'pi' is the Classical Greek letter for lower case 'p', and means 'constant of **P**roportion'.
To find the circumference of a circle the equation is
C = pi d
Circumference equals 'pi' X the diameter.
or
C = 2 pi r
Circumference equals 'pi' X '2' X the radius.

How do you find circumference if you know diameter?
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
How do you find the circumference of a circle from the radius?
Square the radius and multiply the result by 3.14. You may want additional digits of pi for greater precision, but that's the basic idea.The formula is πr² (that's "pi r squared," if the character doesn't show up properly).ANSWER:The above answer is wrong! The above gives the area of a circle, not the circumference. Besides pie are round, cornbread are square. Pi = 3.1416 as stated above.The circumference of a circle is 2 times the radius times pi .This is because pi for all circles is the circumference divided by the diameter. So, pi times the diameter equals the circumference. The diameter is twice the radius.
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.
How do you find the value of pie?
the value of pie is ALWAYS 3.14 The deliciousness of pie gives it it's value. In mathematical terms, pi is the ratio of the circumference to the diameter of a circle.
What is a pie in mathematics?
pi in mathematics is used to determine the circumference of a circle. if you take a piece of string the length of the diameter of the cicle it would go around the circle 3.14159265358978 times (pi).
How do you find the circumference with the pie formula?
circumference = pi multiplied by the diameter
How do you find the circumference if you have a diameter?
pie times diameter
When do you need to use circumference?
The formula is Pie*Diameter
What to do using circumference?
take pie times pie and times the diameter
In order for the circumference of a circle to equal pie what should the radius be?
It is not pie. That is something you eat. It is pi. Your formula is Circumference = pi times Diameter. Diameter = radius times 2. If you replace Circumference with pi then what do you get? You get pi = pi, or 1 pi = 1 pi. or 1=1. You now know the diameter. if the diameter is 1, what is the radius?
The area of circle if its curcumference is 14?
formula for circumference is : C= pie (times) diameter 14= pie Diameter 14=3.14 diameter so divide by pie on both sides to find the diameter aprox: 4.456 = diameter formula for area is : a= pie radius ^2 so find the radius which is half the diameter 4.456/2 =2.228 = radius square the radius 2.228^2= 4.964 times by pie area= 15.597
How do you find circumference if you know diameter?
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
How do you find the the circumference of a circle?
The formula is pi multiplied by the diameter
Formula of circumference of a circle?
Circumference = 2*pi*radius or pi*diameter
What is the correct formula for calculating the circumference of a circle?
[2 x pie x radius] or [pie x diameter]
What is the formula to find a circumference if the radius is 4 and the diameter is 8?
pie multiplied by the radius.
Is the circumference 3 times the radius?
No, the formula for a circumference of a circle is 2(pie)r For example, if r is 6, the the circumference is 12(pie)
