Answer:
45.8 degrees
Step-by-step explanation:
We know that the temp before take off is 57.9
We also know the temp decreases every 1,000 feet so
if we are 11,000 feet in the air and divide that 11000/1000=11
We know that the temp drops 11 times
11x1.1=12.1
57.9-12.1=45.8 degrees
6.76 m^2
Large circle area = pi r^2 = pi L^2 = 60.84
then L = sqrt (60.84/pi)
Small circle radius = r = 1/3 L
small circle area = pi r^2
= pi ( 1/3 sqrt (60.84/pi))^2 = 6.76 m^2
the square root of 81 is 9
