First, find the area of the rectangle if the half circle hadn't been removed.
4.4x9.4=41.36
Now, find the area of the full circle.
πx2.2²≈15.21
Divide that by two.
15.21/2=7.605 (round to hundredths, so it would be 7.61)
Now, take 7.61 from 41.36.
41.36-7.61=33.75
Finally, round to the nearest tenth.
Answer: 33.8
