Checking with Formulas

Use Formulas as Tools

Memorize and use key geometry formulas for perimeter, area, and volume. When solving a problem, check your work by plugging in the numbers and seeing if your answer makes sense!

Tips

  • Write out the formula before substituting numbers.
  • Double-check your calculations.
  • Compare your answer to the shape—does it seem right?

Formulas are your friends in geometry—they make calculations quick and accurate!

Examples

  • Calculating the area of a circle using \( A = \pi r^2 \).

  • Finding the volume of a box using \( V = l \times w \times h \).
