Step 1
In this case, the center of the circle is denoted as 'O'. Since the square ABCD is inscribed in the circle, the radius of the circle is equal to half the length of the diagonal of the square. 2) The length of an arc AQB is the distance along the circumference of Show more…

Consider a circle with radius r. Suppose arc ABC subtends an angle of θ If r = 4 cm and θ = 150° the area of the shaded segment is equal to: 1. 1/2(5π/6 -1/2) cm^2 2. (5π/6 -1/2) cm^2 3. 2(5π/3 -1/3) cm^2 4. 4/3(5π - 3) cm^2 5. 1/2(5π - 3) cm^2
