How do i solve this? Find the radius of a circle that has an arc length of 7 feet that subtends an angle of 110 degrees. b) find the area of the sector of the circle described above.
So I converted 110 degrees to radian and got 11/18Pi is the radius 35.98 or is it 3.64. i'm getting confused i guess where the pi is placed to caluclate.

r=3.64609506 feet
Area of sector = 12.76133271
Explanation:
Why change to radians?
Arc length is
Area
Area of sector = 12.76133271
