Write and solve an equation of ratios:
9 ft 22 ft
------- = -----------
h 99 ft
This is appropriate because h is greater than 9 ft.
cross-multiplying, we get
9(99) ft^2 = 22*h*ft
Then h =40.5 ft (which is the height of the building)
Answer: 137π
The usual formula for a circle centered at (a,b), with radius r,
(x - a)² + (y - b)² = r²
The area of the circle is πr², so 137π

Check the picture below.
notice, that one go-around is 2π, or namely 4π/2, and if we go 3π/2 more over, we'd end up at at 4π/2 + 3π/2 or 7π/2.
a couple of coterminal angles will be those in blue, one angle in the first go-around, and another one by simply going around one more time by 4π/2 extra, 7π/2 + 4π/2 is just that one there.
