# Geometry Calculators and Resources

Our geometry calculators and tools can help solve problems with 2-dimensional and 3-dimensional shapes. We also have several tools for solving coordinate and line graphing problems.

## Area Calculator – Find the Area of 10 Geometric Shapes

Find the area of a space by entering the length and width. Area can be found by multiplying length times width.

## Barrel Volume and Capacity Calculator

Calculate the volume of a barrel in cubic feet, cubic inches, cubic meters, and more. Find the capacity of a barrel in gallons and liters.

## Perimeter Calculator

Calculate the perimeter of many different polygons and shapes, such as a square, rectangle, trapezoid, parallelogram, triangle, or circle.

## Rise and Run to Degrees Calculator

Calculate the angle in degrees of a slope given the rise and run of an incline.

## Rise and Run to Percent Calculator

Calculate a slope percentage given the rise and run of an incline.

## Slope Calculator – Find the Angle or Equation of a Line

Calculate the slope of a line that passes through 2 points on a graph. Solve the slope intercept form equation for a line. Find a point given slope and another point.

## Surface Area Calculator – Find the Surface Area of Many Shapes

Find the surface area of an object, including a cube, rectangular prism, cone, cylinder, and capsule.

## Volume Calculator – Find the Volume of Several 3-Dimensional Shapes

Calculate volume of common three-dimensional shapes, such as a cube, prism, cone, cylinder, pyramid, or capsule, and see formulas. Learn about finding the volume of an irregular shape.
