the diagram Shows a sector of a circle radius 10cm and angle 135 degrees find out area     

 

The area of a circle is π • radius² 

 

The radius of the circle is 10 so the area of the entire circle would be 3.14 • 100 = 314 

 

There are 360^o in an entire circle so the segment would contain 135 / 360 of the circle  

 

(135/360) • 100 = 37.5 

 

Since the radius was given in cm, the area of the 135^o sector of the circle is 37.5 sq cm
