Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
Answer: 1/3piex^2
3rd one down
Step-by-step explanation:
I’m not positive sorry if I’m wrong
Your answer is 20
As isosceles triangle has two angles similar
And sum of all angles is 180,
so
80 + 80 = 160
and
180 - 160 is
20
So ur answer is 20
