Answer:
8πcm² = 8pi cm²
Step-by-step explanation:
The formula for area of a sector = ½r²θ
Where r = radius = 6cm
θ = central angle = 4pi/9 in radians = 4π/9
Area of the sector = 1/2 × 6² × 4π/9
Area of the sector = (144π/18)cm²
Area of the sector = 8πcm²
Therefore, Area of the sector =
8πcm² = 8pi cm²
Add the two equations together
2x+5y+6x-5y=17-9
Combine like terms
8x=8
Divide
x=1
Plug the x value in
2(1)+5y=17
2+5y=17
5y=15
y=3
Final answer: (1,3)
