Question

Area of a circular sector Prove that the area of a sector of a circle of radius r associated with a central angle u (measured in radians) is A = 1 /2 r²u.

Two-dimensional figure measured in terms of radius. It is formed by a set of points that are at a constant or fixed distance from a fixed point in the center of the plane. The parts of the circle are circumference, radius, diameter, chord, tangent, secant, arc of a circle, and segment in a circle.
