Circular Sector Area

Equation and meaning

\[S = \frac{1}{2} \cdot {r}^{2} \cdot \theta\]

Circular Sector Area Where : S is the Surface Area,r is the Radius,θ is the Slant Angle ,

Variables in this formula

r — Radius
Radius SI unit: m
S — S
Enter this value unless it is the selected unknown.
theta — Angle
Angle SI unit: rad

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
