How To Find Area Of Circular Segment
For that we join the end points of the chord with the center of the circle resulting in a sector which subtends some angle at the center. AREA OF CIRCLE AREA OF MINOR SEGMENT Because what is left over from this sum will be the area of the major segment.

Find the area of the triangle using the formula 12 r 2 sin θ.
How to find area of circular segment. It can also be found by calculating the area of the whole pie-shaped sector and subtracting the area of. Area of the circle πr2 31415 152 31415 225 7065 square cm Area of the major segment area of the circle area of the minor segment 7065 204 6861 square cm. Formula To Calculate Area of a Segment of a Circle.
A ½ r 2 θ Sin θ Area of a Segment in Degrees. L - arc length h- height c- chord R- radius a- angle. Find the area of the whole sector find the area of the triangle within the sector subtract the area of the triangle from the.
Area of a Segment in Radians. These formulas shown above for the area of a minor segment also help when trying to find the area of a major segment as the sum would be. Illustrated in the image below.
Identify the central angle made by the arc of the segment and label it θ. The area A and the perimeter P of a circular segment can be found with these formulas. Here are the steps to find the area of a segment of a circle.
A ½ r 2 π180 θ sin θ. Begin split A frac phi-sin varphi 2 R2 P L L_ AB end split where L the arc length and L AB the chord length. To calculate the area of a segment we will need to do three things.
If you know radius and angle you may use the following formulas to calculate the remaining segment parameters. The formula to find the area of the segment is given below. Area of the segment.
Identify the radius of the circle and label it r. How to Calculate the Area of a Segment of a Circle To calculate the area of a segment bounded by a chord and arc subtended by an angle θ first work out the area of the triangle then subtract this from the area of the sector giving the area of the segment. And a perpendicular is drawn from the center of the circle on the chord AB.
The Area of an Arc Segment of a Circle formula A ½ r² θ - sin θ computes the area defined by A f rθ A f rh an arc and the chord connecting the ends of the arc see blue area of diagram. Circular segment - is an area of a cut off circle from the rest of the circle by a secant chord.
