C, GHI because it is over 180 degrees and no triangle is over 180 degrees
Answer:
Area of the sector = 57.26295cm²
Step-by-step explanation:
Radius of the circle=9cm
π= 3.142
Angle at B= 81° ( opposite angle of a quadrilateral)
Area of the sector = πr² * 81/360
Area of the sector = 3.142 * 9*9 * 0.225
Area of the sector= 3.142*81*0.225
Area of the sector = 57.26295cm²
Thye have to have like denominators.
So it becomes, 6/15+5/15 which is equal to 11/15
Answer:
