A plane flying with a constant speed of 29 km/min passes over a ground radar station at an altitude of 15 km and climbs at an angle of 45 degrees. At what rate is the distance from the plane to the radar station increasing 5 minutes later

At 28.93 km/min is the distance from the plane to the radar station increasing 5 minutes later

Step-by-step explanation:

We are given A plane flying with a constant speed of 29 km/min passes over a ground radar station at an altitude of 15 km  

Refer the attached figure

x=15

We will use cosine law

z=155.96 km

Differentiating  1 w.r.t t

Hence  At 28.93 km/min is the distance from the plane to the radar station increasing 5 minutes later

i dont know sorry

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
