Circumference of a circle: 2*pi*radius or diameter*pi
In order to calculate the circumference of a circle one must use a specific formula. The mathematical formula is C = D x 3.14. This translates to the circumference being equal to the diameter multiplied by 3.14, which is the equivalent to pi.
c=πd
the formula is: circumference= p*diameter
Circumference of a circle = (pi) x (diameter)
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
Formula: diameter = pi / circumference
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
It is NOT a formula but an EQUATION . The answer is C = pi*d This equation has been known for thousands of years. It can also be in the form of C = 2 pi r NB 2r = d Also A = pi r^(2) for the area of a circle.
circumference of a circle = pi * diameter.
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter
Circumference = (diameter) multiplied by (pi)
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
In order to calculate the circumference of a circle one must use a specific formula. The mathematical formula is C = D x 3.14. This translates to the circumference being equal to the diameter multiplied by 3.14, which is the equivalent to pi.
