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
.
