Geometry
Circle Sector Calculator
Compute the area and arc length of a circle sector given a radius and central angle in degrees or radians. Use it for pie-chart segments, pizza slices, irrigation pivot coverage, or any circular region problem.
Fill in the required fields to see your result.
Geometry
Triangle Area Calculator
Calculates the area of any triangle from its base and perpendicular height using A = ½·base·height. Perfect for geometry homework, land surveying, construction layout, and architectural design when the perpendicular height is known.
