Area of a circle = 3.14 x r^2
=3.14 x 8.5^2
= 226.865
2x-2y
I couldn’t tell if the first figure was a one or a L or i so I solved it as a 1
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
