It is given that the radius of circle is 8 cm.
Angle substended by the sector = 126 degree
The expression for the area of sector is :
[tex]\text{ Area of sector = }\frac{\theta}{360}\times\Pi\times radius^2[/tex]
Substitute the value of angle = 126 and radius = 8
[tex]\text{ Area of sector = }\frac{\theta}{360}\times\Pi\times radius^2[/tex]
