Answer:
(9 / 10) * PI radians = .9 * PI = 2.8274333882 radians
Sector Area = Central Angle in Radians / 2 * radius^2
Sector Area = 2.8274333882 / 2 * 5 * 5
Sector Area = 1.4137166941 * 25
Sector Area = 35.3429173525
Using degrees:
Sector Area = (162 degrees / 360) * PI * radius ^2
Sector Area = .45 * PI * 25
Sector Area = 35.342917352
