Derive the area of a circle
WebSubstitute 2 times the radius for the diameter. A regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. The polygon area can be expressed in terms of the area of a triangle. Let s be the side length of the polygon, let r be the hypotenuse of the right triangle, let h be the height of the triangle, and WebThe area of a circle is the space enclosed within the boundary of one circular. Computers is calculated using the formula A = πr^2, where 'r' is the radius of the coterie. It is measured in square units.
