To calculate the area of a sector, a simple formula can be used. Sector Area Formula The area of a sector can be found using the formula: sector area = 1 / 2r²θ Thus, a sector’s area is equal to the radius r squared times the central angle θ in radians, divided by 2...
The radius can be expressed as either degrees or radians, with our area of a sector calculator accepting only degrees for now (let us know if it would help you if it supported radians as well). π is, of course, the mathematical constant equal to about 3.14159. Area of a Sector ...
Area of sector is the amount of space enclosed within the boundary of a sector. Explore and learn more about the area of a sector formula, with concepts, definition, examples, and solutions.
The arc length s of a segment is equal to the radius r times the central angle θ in radians. Again, as with most of the above equations, the central angle must be in radians, not degrees. You might also be interested in our sector area calculator for solving the parts of a sector...
Sector Area = ½ × r2×θ r = radiusθ = angle in radians Note: h is at right angles to b Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height We know w = 5 and h = 3, so: Area = 5 × 3 = 15 Example: What is...
