Given:
Area of a sector = 
Radius = 5 cm
To find:
The central angle.
Solution:
The area of a sector is:
Where, r is the radius and 
is the central angle in radians.
Putting 
in the above formula, we get
Multiply both sides by 2.
Divide both sides by 25.
Therefore, the central angle in radians is 
.
