WebbWe know that the circumference of the circle is 2 π r, where r is the radius, but how can we calculate its area? One thing we can do is split the circle into 4 equal wedges (known as sectors), and arrage them edge-to-edge. This results in an unusal, wavy shape, that you can see above. The left and right edges of the wavy shape are both equal ... Webb30 maj 2024 · Then you would apply the formula for finding the area of the circle as follows: A = π (1/2 x D)^2. where "D" is the diameter, and the other variables are as described previously. If the diameter of your circular floor is 4 feet, you would have: A = π x (1/2 x D)^2. A = π x (1/2 x 4 feet)^2. A = 3.14 x (2 feet)^2. A = 3.14 x 4 feet.
