*Area Of Circle*so I'm just going to teach you how to calculate the Area of the Circle .

I'm going to Explain what's Radius ,Diameter and pi.

**Signing Up**

## Step 1: Formula and pi

The Rule is = pi X (R X R)

pi=3.14

how to calculate or pi:

You can Calculate it by Drawing a Large Circle then measuring diameter and Curimefernce then divide the curimefrence by the Diameter

## Step 2: Radius and diameter

Radius : the radius of a circle or sphere is the length of any such segment, which is half the diameter,the radius also refers to the distance from the center of a circle ,sphere cylinder...etc

the radius may be more than half the diameter (which is usually defined as the maximum distance between any two points of the figure).
