If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge.[1] X Research source Example If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm.If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 but you should use your calculator to get the most accurate results.[2] X Research source Example If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm.If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr2, to get the diameter. You can transform this into r = √(A/π) cm.[3] X Research source Example If the area of the circle is 25 cm2, divide that by π and find the ...Familiarize yourself with the use of a compass (the drawing tool, not the direction-finder). This is a very useful instrument in many applications, including drawing a circle's diameter, as outlined above. A divider (an instrument similar to a compass) can sometimes be used in such cases.[6] X Research source Thanks Helpful 3 Not Helpful 2Using geometrical formulas and equations gets easier with practice. Ask for help from someone who has worked with circles or any other geometrical figures. You're likely to find that questions of geometry will seem less challenging with a little experience.

Diameter of a Circle. The diameter of a circle is a line that passes through the center and meets the circumference at opposite ends. It is twice as long as the radius of the circle. In other words, the diameter of a circle is the line that passes through the center and divides the circle into two equal parts. Let us learn more about the ...

Solution: We will use the following diameter formula to find the diameter of the circle. Diameter = 2 × Radius. D = 2 × 24 = 48 inches. Answer: The diameter of the given circle = 48 inches. Example 2: Find the diameter of a circle whose circumference is 8π units. Use the diameter formula.
Aug 3, 2023 · How to Find the Diameter of a Circle Using the Circumference. When the circumference of the circle is known, the equation to calculate the diameter is derived below. As we know, Circumference (C) = πd, here π = 3.141 = 22/7, d = diameter. => d = C / π. Thus, Diameter (d) = C/π. Let us solve an example.
Jul 1, 2024 · We can calculate the diameter by multiplying the radius by 2: d = r × 2. If the circumference is known: The diameter can also be calculated using the circumference: d = c / π. If the area is known: The formula to calculate the diameter from the area of a circle is: d = 2 × √(a / π)
