WebThe enclosed portion of the boundary is called an arc, and the area enclosed by the arc and the two radii is a sector of the circle. The length of the arc is $\qquad \text{Arc length } = r\theta$ The area of the sector is $\qquad \text{Sector area}= \dfrac{1}{2} r^2 \theta$ Note: $2\pi \text{ radians} = 360^{\circ}$. Worked Examples WebThe area, A, of a circle with radius r is A = πr 2.
