The area of the shaded sector is 9π unts²

The term "turn" also refers to a 360° rotation. Angles between 0° and 360° are calculated. We require a circle's circumference, which is equal to 2 r r, where r is the circle's radius.

In any circle of radius r, the ratio of the arc length ℓ to the circumference equals the ratio of the angle θ subtended by the arc at the center and the angle in one revolution. Thus, measuring the angles in radians, ℓ2πr=θ2π⟹ ℓ=rθ.

Find the diagram attached

Given the following

Radius = 6

Theta = pi/2 = 90°

Area of the sector = theta/360×πr²

Area if the sector = 90/360 × π(6)²

Area of the Sector = 1/4 × 36π

Area of the sector = 9π unts²
