12 Area of a Sector What is the area of a semicircle? ½πr 2 What is the area of a quartercircle? ¼πr 2 What is the area of any section of a circle? πr 2 What if we are not given the angle? πr 2 Find the area of a sector with the central angle of 60º and a radius of 10. Express the answer to the nearest tenth. A = πr 2 A = π(10) 2 A = 52.4 Find the area of a sector with an arc length of 40 cm and a radius of 12 cm. A = π(12) 2 A = 240 sq. cm Sep 15 2:14 PM 12

14 Segment of a Circle A segment of a circle is the region bounded by a chord and the arc. Segment Finding the area of a segment of a circle First, you must find the area of a the sector of the circle Second, find the area of the triangle Last, subtract the area of the triangle from the area of the sector to find the segment of the circle In other words: A segment = A sector A triangle Sep 15 3:06 PM 14

15 Find the area of a segment of a circle with a central angle of 120 degrees and a radius of 8. Express answer to nearest integer. Start by finding the area of the sector A = π(8) 2 A = π(64) A = Now, find the area of the triangle. Dropping the altitude forms a degree triangle. Using trig. (or the rules), find the altitude, which is 4, and the other leg, which is 4 3. A = ½ bh A = ½ (4 3)(4) A = We have two triangles, so we have to multiply that by 2. A = A segment = A sector A triangle A segment = A segment = 39.3 Sep 15 3:14 PM 15

16 Terms and definitions Review: A circle is the set of all points in a plane that are equidistant (the length of the radius) from a given point, the center, of the circle. A chord is a segment on the interior of a circle whose endpoints are on the circle. A diameter is a segment between two points on a circle, which passes through the center of the circle. An arc is a connected section of the circumference of a circle. An arc has a linear measurement, which is the portion of the circumference, and an arc has a degree measurement, which is a portion of the 360 degree circle. If a circle is divided into two unequal arcs, the shorter arc is called the minor arc and the longer arc is called the major arc. If a circle is divided into two equal arcs, each arc is called a semicircle. Draw a circle and label the parts listed above Mar 30 11:13 PM 16

17 MM2G4 A secant line is a line that intersects a circle at two points on the circle. A tangent line is a line that intersects the circle at exactly one point. A central angle of a circle is an angle whose vertex is the center of the circle. An inscribed angle is an angle in a circle, whose vertex is on the circle and whose sides contain chords of the circle. A sector of a circle is a region in the interior of the circle bounded by two radii and an Mar 30 11:21 PM 17
