The area enclosed by a circle of radius r is πr 2. Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter. |
The formula for the area of a circle is used by multiplying π by the square of the radius. This can be entered on a calculator in different ways. |
The area of a circle is: π (Pi) times the Radius squared: A = π r 2 or, when you know the Diameter: A = (π/4) × D 2 or, when you know the Circumference: |
Now, we can find the area using the original formula: Area = π × radius × radius; Area = π × 16 × 16; Area = 804.2m2. How to work out the area of a circle ... |
The formula for the area of a circle is A = pi * r * r where r is the radius (diameter / 2). |
Area of a circle. For any circle with radius, r , the area, A , is found using the formula A = π r 2 . For this circle: Diagram of a circle with a 3cm radius. |
The area, A, of a circle can be found by multiplying Pi (3.14) by the radius squared. That is, A = Pi*r^2. |
