Answer:

A = 31.8 cm2

Step-by-step explanation:

Yhe formula:

[tex]A=\frac{\pi r^{2}(Central.Angle) }{360}[/tex]

[tex]r=18/2=9cm[/tex]

central angle = (180-135)° = 45°

[tex]A=\frac{\pi ((9)^{2}(45) }{360} = \frac{\pi (81)(45)}{360} = 10.125\pi cm^{2}[/tex]

[tex]A=31.8cm^{2}[/tex]

Hope this helps
