Areas and volumes of figures

A calculator of areas, perimeters and volumes of the most common figures. For plane figures it computes area and perimeter — e.g. a circle:

$P=\pi r^2 \qquad L=2\pi r$

For solids — the total surface area and the volume, e.g. a sphere and a cylinder:

$V_{sphere}=\tfrac{4}{3}\pi r^3 \qquad V_{cylinder}=\pi r^2 h$

Pick a figure, enter the dimensions — you get all the quantities at once. Results are in units matching the input (area in square units, volume in cubic units).
