Find the area of the sector shown
WebWhen angle of the sector is 2π, area of the sector i.e. the whole circle is. A = π r 2. When the angle is 1, the area of the sector is: A = π r 2 2 π = r 2 2. So, when the angle is θ, area of the sector is: A = θ × r 2 2. A = l r × r 2 … WebQuestion: Which of the following could be used to calculate the area of the sector in the circle shown above? a.π (5in) b. π (5in)2 c. π (30in)2 d. π (30in) Which of the following could be used to calculate the area of the sector in the circle shown above? a.π (5in) b. π (5in) 2. c. π (30in) 2. d. π (30in)
