Geometry Calculator
Calculate area, perimeter, volume, and other geometric properties
Geometry Formulas
Rectangle:
- • Area = length × width
- • Perimeter = 2(length + width)
- • Diagonal = √(length² + width²)
Circle:
- • Area = π × radius²
- • Circumference = 2π × radius
- • Diameter = 2 × radius
Triangle:
- • Area = ½ × base × height
- • Perimeter = side1 + side2 + side3
3D Shape Formulas
Sphere:
- • Volume = (4/3)π × radius³
- • Surface Area = 4π × radius²
Cylinder:
- • Volume = π × radius² × height
- • Surface Area = 2π × radius × (radius + height)
Cube:
- • Volume = side³
- • Surface Area = 6 × side²
- • Diagonal = side × √3
