find area of major segment
About that much
area of circle minus area of minor segment.
To find the area of a major segment, you need to know the radius of the circle and the angle subtended by the major segment at the center of the circle. Here's how you can calculate it:
1. Determine the radius of the circle: This is the distance from the center of the circle to any point on its circumference. If the radius is not given, you will need that information to proceed.
2. Determine the angle subtended by the major segment: This is the angle formed by the two radii that intersect at both endpoints of the major segment. Make sure the angle is given in radians, not degrees. If the angle is given in degrees, you can convert it to radians by multiplying by π/180.
3. Use the formula for the area of a major segment: The formula is A = (θ - sinθ) * r² / 2, where A is the area, θ is the angle (in radians), and r is the radius.
4. Plug in the values: Substitute the values of the radius and the angle into the formula.
5. Calculate the area: Once you have substituted the values, evaluate the expression to find the area of the major segment.
Remember to use the appropriate units for the radius and area, depending on the context of the problem.
