Answer:
11.5 square unit, 11.5 square wnit
49.8 squave unit, 49.8 square unit
Step-by-step explanation:
[tex]When\ x=3,y=\frac{2}{3}\times3+3=5.[/tex]
[tex]\tan{\theta}=\frac{2}{3}\Rightarrow{\theta}=33.69\ degrees[/tex]
[tex]A_1=\pi(R^2-r^2)\bullet\frac{33.69\ degrees}{360\ degrees}\\ =\pi(64-25)\bullet\frac{33.69\ degrees}{360\ degrees}\\ =11.5[/tex]
[tex]A_2=\pi(R^2-r^2)\bullet\frac{180\ degrees-33.69\ degrees}{360\ degrees}\\ =\pi(64-25)\bullet\frac{146.31\ degrees}{360\ degrees}=49.8[/tex]
[tex]A_3=A_1=11.5\\ A_4=A_2=49.8[/tex]
[tex]elementany\ calculation[/tex]
I hope this helps you
