This Circles Unit Bundle contains guided notes, homework assignments, three quizzes, a study guide and a unit test that cover the following topics: • Identifying Parts of Circles: Center, Radius, Chord, Diameter, Secant, Tangent, Central Angle, Inscribed Angle, Minor Arc, Major Arc, Semicircle. • Area and Circumference. Hence, it can be concluded that an arc of length l will subtend l/r, the angle at the centre. So, if l is the length of the arc, r is the radius of the circle and θ is the angle subtended at the centre, then; θ = l/r, where θ is in radians. When the angle of the sector is 2π, then the area of the sector (whole sector) is πr 2.
