Sector Area Formula

Formula variable explanation:

  • S represents the area.
  • θ represents the Angle.
  • r represents the Radius.

LaTeX formula

If you are working in a TeX based editor you could use this TeX formula to calculate the sector area.

\mathrm{S}=\frac{ θ}{360}\cdot\pi\cdot{ r}^{2}

How To Calculate The Sector Area Your Self

Calculating the area is rather simple when you know the formula presented above. Follow these steps:

  1. Write down this formula:

  2. Then change the following variables with your values:
    1. θ shall be changed with the Angle of your sector. As an example θ could be changed to 10.
    2. r shall be changed with the Radius of your sector. As an example r could be changed to 10.
  3. Now you can enter this in to your calculator and you will get your answer.
