Area Calculator

Area = π × radius². Example: a circle with radius 5 cm has area = 3.14159 × 25 = 78.54 cm².

Area = ½ × base × height. Example: a triangle with base 6 m and height 4 m has area = ½ × 6 × 4 = 12 m².

You can enter any unit (meters, feet, inches, cm, etc.) as long as all dimensions use the same unit. The result will be in square of that unit (e.g., m² or ft²).
