As the angle (35 degrees) and the radius (1.1) of the sector are given, you need to find the area of the sector. I think the problem is asking you to do that.
The area of a sector is equal to (1/2)(r^2)(θ), where r is the radius and θ is the angle in radians.
In order to use this formula we need to convert degrees to radians.
360 degrees = 2 pi radians
1 degree = (2 pi)/360 = pi/180 radians So,
36 degrees = 36(pi/180)= pi/5
Thus,
(1/2)(r^2)(θ) = (0.5)(1.1)^2(pi/5) ≈ 0.38

How do you find the area of a circle to the nearest hundredth?
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
