In terms of circumference, the **diameter** can be computed using the equation d = c/pi, where "c" represents the circumference and pi is approximately equivalent to 3.142. If the **area** of the **circle** is given, the formula d = sqrt (4a/pi) can also be used to solve for the **diameter**, where "a" denotes the **area**.

The formula for the area of a circle is **pi multiplied by the radius of the circle squared**. The radius of the circle is the length of a straight line stretching from the center of the circle to the line of circumference.

To **find** the **area** of a **circle**, you take pi times the **radius** squared, or A = pi r^2. Using this formula, you can **find** the **area** of a **circle** if you know the **radius** -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.14.

Methods to derive the formula for Area of Circle Method 1. A circle of radius R can be imagined to be constituted of a large number of thin circular rings/strips (which are concentric) with continuously varying radii as shown ... Method 2. ... Method 3. ...
