WebJun 27, 2024 · Solved Example 1: Determine the length of the arc if the radius of the circle is equal to 4cm and the angle formed by the arc is equal to π/8 radians. Solution: Given; Radius of the circle = 4cm. Arc angle=π/8. The arc angle is in radians thus, Using the arc length formula i.e. = L = θ x r. L = π 8 × 4. WebA sector of a circle is called the minor sector if the minor arc of the circle is a part of its boundary. It is the sector with a smaller area. The angle of a minor sector is less than 180 degrees. Major Sector A sector is called the major sector if the major arc of the circle is a part of its boundary. It is the sector with the greater area.

WebMar 29, 2024 · 4. Multiply the radius by the arc’s central angle. The product gives you the length of the arc. For example: arc length = 2.36 ( 10) = 23.6 {\displaystyle {\text {arc length}}=2.36 (10)=23.6} So, the length of an arc … WebAll steps. Final answer. Step 1/3. A radius is any line segment that connects the center of a circle to a point on the circle's circumference. A diameter is a chord that passes through the center of a circle. A chord that is not a diameter is any line segment that connects two points on a circle's circumference. View the full answer.
