Volume of Cylinder V = πr²h
diameter = 6 feet, radius = 6/2 = 3 feet
dV/dt = (dV/dh) * (dh/dt) by change rule.
V = <span>πr²h
dV/dh = </span>πr² = π*3² = 9π ft²<span>
dV/dt = 2 ft</span>³/min
<span>dV/dt = (dV/dh) * (dh/dt)
</span>
2 ft³/min = 9π ft² * (dh/dt)
9π ft² * (dh/dt) = 2 ft<span>³/min
</span>
(dh/dt) = (2 ft³/min)/(9π ft<span>²)
(dh/dt) = (2/</span>9π) ft/min
So the water level is rising at (2/9<span>π) ft/min.</span>
What 1+1= ??? I can’t figure it out
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D
Answer:
15 min
Step-by-step explanation:
Julia spends 
in math.
and spends 
in spelling.
Lets make 
for calculation propuses.
Julia spends 
doing her math and spelling homework.
And lets make 
and 
So, Julia spends 
in reading.
If I divide an hour into 4 equal units, each unit equals 15 min, so 1 unit is 15 min.
Julia spends 15 min in reading.
Answer:
0.1
Step-by-step explanation:
To set this question up:
1/2 / 5
To solve this turn 5 into 5/1. Then multiply by the reciprocal. (1/5) 1/2 times 1/5 is 0.1
