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.
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. :)
Well, isn't that just a happy little question! The diameter of a circle with a circumference of 27cm can be found by using the formula C = πd, where C is the circumference and d is the diameter. So, if the circumference is 27cm, you can plug that into the formula and solve for the diameter. Just remember, there are no mistakes, only happy little accidents in math!
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.
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.
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.
circumference = pi multiplied by the diameter
pie times diameter
The formula is Pie*Diameter
take pie times pie and times the diameter
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?
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
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. :)
The formula is pi multiplied by the diameter
Circumference = 2*pi*radius or pi*diameter
[2 x pie x radius] or [pie x diameter]
pie multiplied by 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)
