#### Formula:

a = π × r × r × c / (360 × 43560)
**Where,**
a = Circular Field Area
r = Radius(ft)
c = Portion of the Circle
### Example:

Calculate the area of circular field with the radius and the portion of the circle be 50 ft and 10°.

#### Solution:

a = π × 50 × 50 × 10 / (360 × 43560)

=0.005 acre
