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
