5000.pi=4/3.pi.r^3
r^3=3750
r=15,53
Surface Area=4pir^2
Surface Area =4.pi. (15,53)^2
Surface Area =964,72.pi
Answer:
d
Step-by-step explanation:
the slope is change in y over change is x and as y goes down 5 x goes up 3
so -5/3 is the slope

Answer:
dy/dt = - (1/5) ft/s = - 0.2 ft/s
Step-by-step explanation:
Given
L = 5 ft
Qin = 25 ft³/s
Qout = 30 ft³/s
h = 10 ft
dy/dt = ?
We can apply the relation
ΔQ = Qint - Qout = 25 ft³/s - 30 ft³/s
⇒ ΔQ = - 5 ft³/s
Then we use the formula
Q = v*A
where Q = ΔQ, A = L² is the area of square base and v = dy/dt is the rate of change in the depth of the solution in the tank
⇒ ΔQ = (dy/dt)*L²
⇒ dy/dt = ΔQ/L²
⇒ dy/dt = (- 5 ft³/s)/(5 ft)²
⇒ dy/dt = - (1/5) ft/s = - 0.2 ft/s
Answer:
4t - 3 > 37t - 50
Step-by-step explanation:
Step 1: 4t - 3 > 37t - 50
<u>-4t -4t</u>
-3 > 33t - 50
<u>+50 + 50</u>
<u>47</u> > <u>33</u>t
33 33
<em>t < 47/33</em>
