Circumference equals the diameter multiplied to 'pi'.
Algebraically it is written as
C = pi d
NB 'pi' is an irrational number , of the value 3.141592.... Approximated to 3.14 or 3.1416

How does an architect use pi?
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
What is the circumference of a 35 ft diameter circle?
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 35 feet, so the circumference would be C = π(35) = 110.19 feet.

How do you calculate circumference of a circle?
You use a protractor.
Why you are using pi to calculate circumference of the circle?
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
How do you calculate the diameter and the circumference of a circle?
Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.
How do you calculate the circumference of a circle given the diameter or the radius?
Circumference = diameter*pi
IF the circumference of a circle is 6.28 what is the area?
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
What is the ciruumference of a circle?
The circumference is essentially the perimeter of the circle, or the distance around the circle. To calculate the circumference of a circle, use the formula C = 2 * pi * r. Circumference = two times pi times the radius of the circle.
Why do we use pi?
The ancient civilisations, 4000 years ago, Sumerians, calculated 'pi' to be 3.141592..... The story goes ; A donkey on a tether ( radius) was driven around in a circle (Circumference) to drive water up from a well. They noticed that however, long the tether (radius) was , the correspodning circle(circumference) was always in the same ratio. ; pi = 3.141592..... This can be mathematically expressed as Circumference is directly proportional to the diameter. or 'C' is directly proportional to 'd ' This can be equated with a constant C = k d Algebraically rearranged as k = C/d Whatever the dimensions of a given circle were/are 'k', the constant, was always found to be 3.141592.... Much later after the Sumerians, the Classical Greeks, gave the name 'pi' to this constant. 'pi' being the lower case classical Greek letter 'p' and refers to **P**roportion. Hence 'pi' , today is used as this constant of proportion for circles. 'pi' is an irrational number, which means in casual terms, the decimal digits go to infinity and there is no regular order in the decimal digits. On 'Supa-Dupa' computers' pi' has been calculated to some 50 billion places and still going. NB Remember the circle equations. C = pi d C = 2 pi r ( d = 2r) A(area) = pi r^(2) When learning circle calculations you are probably given pi as 3.14, or .3.1416. or 22/7, but these are only approximate values, and NOT exact values. Hope that helps!!!!!
