One tool for the seven most-used shapes: rectangles, circles, triangles, cubes, spheres, cylinders, and cones. Choose the shape, enter its dimensions, and get area, perimeter, volume, or surface area as applicable.
Area, perimeter, volume, and surface area for seven shapes instantly.
Rectangle: A=lw, P=2(l+w) · Circle: A=πr², C=2πr · Triangle: ½bh · Cube: s³, 6s² · Sphere: ⁴⁄₃πr³, 4πr² · Cylinder: πr²h · Cone: ⅓πr²h
| Symbol | Meaning |
|---|---|
| l, w | Rectangle length/width |
| r | Radius (circle/sphere/cylinder/cone) |
| s | Cube side |
Rectangle 5×3 → area 15, perimeter 16. Sphere r=2 → volume ≈ 33.5103, surface ≈ 50.2655.
