In the given image, R R R is the radius and α \alpha α is the central angle in radians for a sector of a circle. Which of the following is the correct equation for the area of the sector of the circle?

A = R 2 α 2 A=\frac{R^2\alpha}{2} A = 2 R 2 α

A = R 2 α A=R^2\alpha A = R 2 α

A = R α 2 A=\frac{R\alpha}{2} A = 2 R α

In the given image, RRR is the radius and α\alphaα is the cen...
