How This Calculator Works
This calculator handles common 2D and 3D shapes. For a circle, dimension A is the radius. For a rectangle, A is length and B is width. For a triangle, A is base and B is height.
Formula
Circle: πr², 2πr; Rectangle: l×w, 2(l+w); Sphere: 4πr², ⁴⁄₃πr³
Example
A circle of radius 5 has area ≈ 78.54 and circumference ≈ 31.42.
