Answer:
Arc length is equal to 
where 
is the angle in radians and 
is the radius.
Question 1:
So the angle is CFD.
Question 2:
So the angle is AFE.
Question 3:
So the angle is AFB.
Question 4:
So the angle is BFC.

Answer:
29.5 square inches
Step-by-step explanation:
Let's divide the shape into 3 parts to make it easy for us to find the area.
- a wide triangle
- a triangle
- a shorter rectangle
For the wider rectangle, the area is;
A1 = 8 × 2 = 16 in²
For the triangle, the area is;
A2 = ½(7 - 2) × 3
A2 = 7.5 in²
For the shorter rectangle, the area is;
A3 = 3 × 2
A3 = 6 in²
Total area = A1 + A2 + A3 = 16 + 7.5 + 6 = 29.5 square inches
