2 days ago · To calculate the circumference of a circle with a radius of 1 meter, simply follow these steps: Multiply the radius by 2 to get the diameter of 2 meters. Multiply the result by π, or 3.14 for an estimation. And there you go; the circumference of a circle with a radius of 1 meter is 6.28 meters.
Thus, we can define three different formulas to find the perimeter of circle (i.e. circumference of a circle). Formula 1: When the radius of a circle is known. Circumference of a circle = 2πr. Formula 2: When the diameter of a circle is known. Circumference = πd
Jul 20, 2023 · To calculate the circumference of a circle, use the formula C= pi*D where C is the circumference, D is the diameter and pi is 3.14. If you have the radius instead of the diameter, multiply it by two to get the diameter.

The Formula of the Circumference of Circle. The circumference, [latex]C[/latex], of a circle is calculated by multiplying pi [latex]\color{blue}\large{\pi}[/latex] by the diameter [latex]\color{red}\large{d}[/latex].
The formula for circumference is based on the constant π (pi), which is an irrational number approximately equal to 3.14159. π is the ratio of the circumference to the diameter of any circle. Since π = C/d, where C is circumference and d is diameter, we can derive the circumference formula as follows:
The formula for the circumference of a circle is expressed using the radius 'r' of the circle and the value of ' pi '. It is expressed as, Circumference of a circle formula = 2πr. While using this circumference formula, if we do not have the value of the radius, we can find it using the diameter.
Given the radius of a circle, the circumference can be calculated using the formula where: R is the radius of the circle π is Pi, approximately 3.142 See also Derivation of circumference formula
