After flying at an altitude of 650 meters, a helicopter starts to descend when its ground distance from the landing pad is 2 kil
ometers. What is the angle of depression for this part of the flight
1 answer:
Answer:
The angle of depression is 18.0°
Explanation:
From the question the flight path of the plane is a right angle triangle where the height is 650meters and the length is 2km
Converting 2km to meters gives 2000meters
Therefore the angle of depression = Tan^-1(650/2000)
Angle of depression = Tan^-1(0.325) = 18.0°

Explanation:
The area of a circle is given b
A=πr²
Then,
dA/dr= 2πr
Also give that,
dr/dt=30m/hr, r=100m
We want to find dA/dt
dA/dt=dA/dr×dr/dt
dA/dt= 2πr × 30
dA/dt= 2 ×π ×100×30
dA/dt=18849.56m²/s.
The rate of the area is 18849.56m²/s
