Answer: 2 minutes
Step-by-step explanation:
Given the following :
Plane A's descent :
y = -2,500x + 14,000
Plane B's Ascent :
y = 4,000x + 1,000
where y = altitude x = minute
Time to be at the same altitude :
Being at the same altitude means ;
Plane A's descent = Plane B's Ascent
-2,500x + 14,000 = 4,000x + 1,000
-2500x - 4000x = 1000 - 14000
-6500x = - 13000
x = 13000 / 6500
x = 2
x = 2minutes.
You line them up from smallest to greatest

Answer:
628
Step-by-step explanation:
So the formula is πr^2h/3
So the height is 6
pie is 3.14
Substitute:
3.14(10)^2 6/3
3.14(100)(2)
3.14(200)
628
