As per the formula deduct the value of th by the value of sinth and multiply the value by the squared value of radius. You can also find the area of a sector from its radius and its arc length. Let R be the radius of the circle th the central angle in radians a is the central angle in degrees c the chord length s the arc length h the sagitta height of the.
The formula for area A A of a circle with radius r and arc length L L is.
Total Circle Area p r2 Radius of circle r D2 Dia 2 Angle of the sector th 2 cos -1 r h r. The below given is the area of segment of circle formula to calculate the area of circle segment on your own. If the angle is th then this is th2p the fraction of the full angle for a circle. As per the formula deduct the value of th by the value of sinth and multiply the value by the squared value of radius.
