## How To Find The Area Of A Sector In Radians

Find the area of a sector whose angle is \(117^\circ \) in a circle of radius \(3.5 \) m. Solution: As with arc length, we have to make sure that the angle is measured in radians …

- Find the lengths of the arcs s and s’ in the figure if r = 4 and θ‘= 60°. Solution: To find the arc length, s, first we have to find the angle θ that subtends the arc s,
- Additionally, we will see how right triangles and fractions can help us find the Area of a Sector, which, according to Cool Math, is the area between two segments coming out of the center of a circle.
- The total area of a circle is π r 2. The area of the sector can be obtained by multiplying the circle's area by the ratio of the angle and 2 π (because the area of the sector is proportional to its angle, and 2 π is the angle for the whole circle, in radians):
- This video offers a tutorial on how to find the area of a sector given the radius of the circle and the degree measure of the central angle. • Texas Instruments.“Radian Measure.”
