➗ Math Formula Calculator

Formula Circle Area — A = π × r² Circle Circumference — C = 2 × π × r Rectangle Area — A = l × w Rectangle Perimeter — P = 2 × (l + w) Square Area — A = s² Triangle Area — A = ½ × b × h Pythagorean Theorem — c = √(a² + b²) Quadratic Equation — x = (−b ± √(b²−4ac)) / 2a Simple Interest — SI = (P × R × T) / 100 Compound Interest — A = P × (1 + R/100)^T Cylinder Volume — V = π × r² × h Sphere Volume — V = (4/3) × π × r³ Permutation — nPr = n! / (n − r)! Combination — nCr = n! / (r! × (n − r)!)
