Question

The central angle of a circle measures 100 degrees, while the area of the sector including that angle is 40pi. What is the length of the radius of the circle?

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.
