### Google can solve geometry problems

If you frequentely need to solve geometry problems, you'll already know you can use the amazing Wolfram Alpha (for that and lots more - although if you do, you'll probably trust yourself you know how to do it right without external help). But sometimes you may just need a quick answer or validate that you haven't forgot your math lessons from eons ago, and for that you may like to know that Google can also answer your math questions.

There's a whole section dedicated to geometry, with fórmulas, 2D shapes and even 3D objects calculations, with interactive widgets you can quickly and easily play around to find out what you need.

Areas, edges, volume, sheres and cylinders, prisms and even dodecaedron calculations are just a question away:
• [what is the volume of a cylinder with radius 4cm and height 8cm]
• [diagonal of a rhombus calc]
• [formula for a triangle perimeter]
• [hypotenuse calc]
• [how do I calculate triangular prism volume?]
• [find the diameter of a sphere whose volume is 524 gallons]
• [a^2+b^2=c^2 calc a=4 b=7 c=?]
• [calculate the diagonal of a cube with 6mm edge]
As a shortcut, you can simply enter the name of the shape/object followed by calc, like: sphere calc, cylinder calc, triangle calc, etc. But the most amazing part is being able to simple ask voice questions into your smartphone (soon, a smartwatch) like: find the sides of a cube whose volume is 5 liters.
