Answer: 3y3+7y2+−4y+3
Step-by-step explanation:
3y2+y3+−5+4y2+−4y+2y3+8
Combine Like Terms:
=3y2+y3+−5+4y2+−4y+2y3+8
=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)
=3y3+7y2+−4y+3
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
