Step 1: What You Need
a pencil (or pen whatever you want...)
a protractor and a calculator (or your mind!)
Step 2: The Area of the Circle........well Not Really
(If you already know where is the middle of your circle, skip to step 3)
1st you have to draw a line anywhere around the circle. Make sure the line is outside of the circle but touching the circle (see image two). Next you have to draw a 90 degree angle using your protractor. Do this method until you find the middle (do this 3 or more times).
Step 3: Now It's Time to Find the Area of Your Circle!
Note: The actual abbreviation for inches is "in."
Step 4: Calculating!
Now you know how to calculate the area of a circle!
