The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius If a circle has a radius of 4, its area is 3.14*4*4=50.24 If you know the diameter, the radius is 1/2 as large. Return to Top ...
The area of a circle is:π (Pi) times the Radius squared:A = π r2 or, when you know the Diameter:A = (π/4) × D2 or, when you know the Circumference:A = C2 / 4πExample: What is the area of a circle with radius of 3 m ? Radius = r = 3 Area= π r2 = π× ...
Before we jump into the various formulas for a circle. Let's quickly define what a circle really is and why it's important. The Math Open Reference defines a circle as; "A line forming a closed loop, every point on which is a fixed distance from a center point." However, if you ...
