i(-5i + 6) + 8(3 + 7i)
= -5i^2 + 6i + 24 + 56i
= 5 + 24 + 62i (because -i^2 = 1)
= 29 + 62i

The expression that represent the area of the cut off part is 81π / 4
<h3>How to find area?</h3>
The area of the cut off part can be found as follows:
Area of a circle = πr²
where
Therefore, the cut off part is like 1 / 4th of a circle.
Hence,
area of the cut off region = πr² / 4
r = 9 inches
area of the cut off region = π9² / 4
area of the cut off region = 81π / 4
