Answer:
x = 559.31 m
Step-by-step explanation:
Given in the question,
horizontal distance from airplane to the coral reef = 3172 m
outer angle of depression = 10°
inner angle of depression = 90 - 10
= 80°
It is a question of right angle triangle, we will use trigonometry identity to solve the question
<h3>Tan(80) = base / height</h3>
Tan(80) = 3172 / x
x = 3172 / Tan(80)
x = 559.31 m
A=π(4)2=π·42≈<em>16pi ft^2</em>
