How to Find The Area of a Circle

Finding the Area Of a Circle

Instructions

Difficulty: Moderately Easy

1. Find the radius(a straight line extending from the center of a circle to its edge) of the circle.
2. Square the measurement of the radius.
   Example: If the measurment of the radius was:
   *9 ins.: 9x9=81
   *5.5 cm.: 5.5x 5.5=30.25
3. Then multiply the answer of the squared number by Pi(3.14).
   Example:
   Radius: 9.: 9x9=81 81x3.14=254.34
4. Once you get that answer, put the measurement, (inches, meters, centimeters, etc.) and put the symbol for area (squared), which is 2.
