What is Area of a Circle Explained about?

To find the area of a circle, use the formula Area = π x radius2. For a circle with radius 5, its area is 25π in2. While π is approximately 3.14, estimating the area as 25 x 3.14 gives a close approximation of 78.5 in2 for circles when the exact value of π is unknown. The radius is half the diameter, so if only the diameter is given, divide it by 2 first to get the radius to calculate the area.
