How To Find The Diameter Of A Circle

Well, in this article we teach you How to Calculate the Diameter of a Circle.
If you know any other dimensions of the circle: radius, circle, or area, it is easy to calculate the diameter of the circle. If you do not know any of the above measurement methods, but there is a pie chart, this is also possible. If you want to know how to calculate the diameter of a circle, follow these easy steps:

Here you will learn about How To Find The Diameter Of A Circle By 2 Method

Method 1 of 2:

1st let’s try to Calculating the Diameter of a Circle Using the Radius, Circumference, or Area

How To Find The Diameter Of A Circle

1. If you know the radius of the circle, double it to get the diameter. Radius is the distance from the center of the circle to the edge.

Example(s):

If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm.

 

2. If you know the circumference of the circle, divide it by π to get the diameter. Π is 22/7 = 3.14, but you should use a calculator to get the most accurate results.How To Find The Diameter Of A Circle

Example(s):

If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm.

 

3. 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 can go back to find the formula for the area of the circle, A = πr, to get the diameter. You can transform this into r = √(A/π) cm.How To Find The Diameter Of A Circle

Example(s):

If the area of the circle is 25 cm, divide that by π and find the square root.This equals cm 2.82cm, so the diameter of the circle is 2.82 x 2 = 5.64cm.

Second Method to Calculating the Diameter of a Circle from a Drawing of a Circle

1. Draw a horizontal line from side to side within the circle. Use a ruler or ruler to do this. It can be upstairs, near the bottom or somewhere in between.

2. Label the points where the line crosses the circle points “A” and “B.”

3. Draw two overlapping circles, one centered on A and the other centered on B. Make sure that the two circles overlap like a Venn diagram.

4. Draw a vertical line through the two points where the outer circle intersects. This line marks the diameter of the circle 4.How To Find The Diameter Of A Circle

5. Measure the diameter. Use a ruler or more precisely a pair of digital vernier calipers to measure it. You’re done!How To Find The Diameter Of A Circle
