How to Find The Area of a Circle

    • 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.
