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

Its radius is 4.8 cm, rounded to the nearest tenth.
The radius is 7 rounded to the nearest integer The circumference works out as 44 rounded to the nearest integer.
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth
The area of a circle is: pi times radius squared
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
2000.00
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
10=2*pi*r Solve for r: 10/(2*pi)=r 1.591=r so radius rounded to nearest tenth is 1.6
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.
