This Instructable is for the Burning Questions Round 6.5 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.

Step 1: Formula and Pi

First you need to know what is the Rule or Formula for the Circle because it's the most Important thing and it's also the first step you do to Calculate the Area

The Rule is = pi X (R X R)

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

Diameter: diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle. The diameters are the longest chords of the circle.

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).
