Get PRO version or visit http://geometryplus.com for more free calculators.

Featuring both 2D and 3D geometric shapes and volumes including CIRCLE, TRIANGLE, RECTANGLE, SPHERE, CONE.
Making math easy and fun again!! For both PROFESSIONALS and STUDENTS. Includes features from Geometry++ 2D Edition, Geometry ++ 3D Solid Edition and Geometry ++ 3D Fluid Edition(available soon).
Best designed interface in its class, easy and intuitive to use. Our main goal is ease of use, no long notes, concise and to the point. Saves you time and it is quick! Not bloated with unnecessary features that you will never use.

Get Geometry ++ : 3D Solid which allows you to calculate VOLUMES, SURFACE AREAS, circumference / perimeter, cross-sectional areas
and more for basic 3D geometric volumes including:
1. Sphere (included in lite version)
2. Cylinders
3. Cones (included in lite version)
4. Rectangular Prisms
5. Rectangular Pyramids

Geometry ++ : 3D Fluid which is included in the PRO version and allows you to calculate the properties of various pipe cross sections. It calculates the volumes of water in pipes at various depths and includes hydraulic radius and percent full calculations. the following pipe / tank cross-sections are currently supported:
1. Circular pipe (included in lite version)
2. Rectangular pipe (included in lite version)
3. Trapezoidal pipe
4. Triangular pipe

Finally, you can get Geometry ++ : 2D which allows you to calculate sides, angles, lengths, areas,
and perimeters for basic 2D geometric shapes including:
1. Lines
2. Circles (included in lite version)
3. Triangles (included in lite version)
4. Rectangles
5. Trapezoids or Trapeziums

For each of the shapes, entering a minimal set of inputs allows you to calculate
a bunch of unknowns and the results are presented on the same screen!
Works for both METRIC and ENGLISH units because the results are mostly unit-independent!
