The formula for the area of a circle is π x radius2, but the diameter of the circle is d = 2 x r2, so another way to write it is π x (diameter / 2)2. Visual on the figure below: π is, of course, the famous mathematical constant, equal to about 3.14159, which was originally defined as the ratio of a circle's circumference to its diameter. The formul...
Calculation is easy once you have measured the circle's radius or diameter, or if you know it from plans and schematics: just plug the numbers into the formulas above or use our circle area calculator instead. If you are measuring it by hand, remember that the diameter is the largest measurement you can get from a circle.
Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 52= 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. Apply the second equation to get π x (12 / 2)2 = 3.14159 x 36 = 113.1 cm2(square centimeters).
Circle geometry has a wide array of practical uses. Circles are used when planning athletic tracks, recreational areas, buildings, and roundabouts, so knowing their area is important in construction, landscaping, etc. The famous Ferris-wheel attraction is a circle, as are the wheels on your car or bike. Circle-like parts, e.g. cylinders, tubes, gea...
