How To Find The Diameter Of A Circle Using The Area. Area of a circle radius. Find the diameter of a circle if its radius is 3 cm.

In this formula, d is the diameter of the circle. You can also use the diameter (the length from one end of a circle to the other) and the circumference (the length around the outside of a circle) to find the missing length of a radius. Relation between radius and diameter:

### Now Find The Area Of The Circle Using The Formula With Radius As Shown Below;

Find the diameter of a circle if its radius is 3 cm. To solve for the length of the diameter of a circle, substitute values of the radius, circumference, or area into the following equations: We use the circle formula to calculate the area, diameter, and circumference of a circle.

### Relation Between Radius And Diameter:

Take the square root of 7.96: Formula of area of circle in the form of diameter is. Finding the radius of a circle requires you to use formulas such as the area or sector area of a circle formulas.

### 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.step 2, If You Know The Circumference Of The Circle, Divide It By Π To Get The Diameter.

We know that the the distance from the center point to any point on the circumference of a circle is a fixed distance, known as the radius of a circle. Using this definition, the formula for the diameter is d. A = 3.14 x 1 = 3.14 sq.cm.

### You Can Find The Diameter Of A Circle By Multiplying The Radius Of A Circle By Two:

\ (diameter = 2 \times radius\) In this formula, d is the diameter of the circle. The diameter of a circle calculator uses the following equation:

### Diameter = 2 * Radius.

Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. We can also calculate the area directly using diameter. Notice that the calculated area of the circle is same in both the methods.
