Area of a Sector Formula :

$$\text{A}\;=\;\frac{1}{2}θr^2$$

Where,

• A shows Area of a Sector.
• θ is the angle of the sector.
• r is the length of the radius.

$$\text{A}\;=\;\frac{x}{360}πr^2$$

Where,

• A shows Area of a Sector.
• x is the angle of the sector.
• r is the length of the radius.>
