It should be 8473x 38473 93
Answer:
15 (I think)
Step-by-step explanation
6 x 25 = 150
20% of 150 = 30
10% of 150 = 15
30 - 15 = 15
<em>Sorry if this is wrong.</em>
<em>Bye, have a great day/night.</em>

Answer: 15 cubic feet</h3>
Explanation:
18 inches = 18/12 = 1.5 feet
The cabinet is 5 ft by 1.5 ft by 2 ft. Multiply the values to get 5*1.5*2 = 15
We are given with the following given
dV/dt = 35 m3/min
h = (3/2)D
What is asked is
dr/dt at t = 7 min
The volume of a cone is
V = (1/3)πr²h
From the given
h = (3/2)D
since D = 2r
h = 3r
Subsituting
V = πr³
At t = 7 min, the volume is
V = 35(7)
V = 245
and the radius is
245 = πr³
r = 4.27
Differentiating the volume
dV/dt = 3πr² dr/dt
From the given
dV/dt = 35
Subsituting
35 = 3πr² dr/dt
So,
dr/dt = 0.20 m/s
and
dh/dt = 0.60 m/s
