Answer:
h = 452.5 ft
Step-by-step explanation:
Angle of elevation from P to top of the pole = 65°
Horizontal distance between the pole and point P = 21 ft
By Applying tan rule in the given triangle ABP,
tan(∠APB) = 
tan(65°) = 
h = 21[tan(65°)]
h = 452.491
h ≈ 452.5 ft
Therefore, height of the pole is 452.5 ft.
Area of semicircle = (πr²) ÷ 2
Area of semicircle:
= (3.14)(2)² ÷ 2
= (3.14)(4) ÷ 2
= 12.56/2
= 6.28
The expression simplifies to 6x^(28/5)
hope this helps :)
