Math
Pythagorean Theorem Calculator
Find the hypotenuse of a right triangle from its two legs using a² + b² = c². The cornerstone of geometry, trigonometry, and distance measurement.
Geometry
Circle Area Calculator
Calculates the area enclosed by a circle from its radius using A = π·r². Ideal for geometry homework, landscaping projects, or sizing circular spaces like pools, garden beds, or pipe cross-sections.
