A conical water tank is 24 ft high and has a radius of 10 ft at the top. If water flows into the tank at a rate of 20 cubic feet
Akimi4 [234]

Answer:

0.027 cubic ft/min

Explanation:

Volume of water is V=V(t) Depth of water is h=h(t)

The relationship between V and h is

V=π/3.r2.h

Let

h0= the height of the cylinder = 24ft, r0= the radius of the opening = 10ft.

Since water level (h) rise with respect to flow rate we find an expression for r and substitute into V

r/h = r0/h0= 10/24 = 5/12

r = (5/12) h,

Substitute for r in V

so,

V=1/3.π.(h2)square = 1/3.π. 25/144.(h3)

When

h= 16ft

and dV/dt = 20ft3/min

,

dV/dt =1/3*π*25/144*h3*(dh/dt)

20ft3/min= 1/3*π* 25/144*h3*(dh/dt)

20 = 1/3*π*(16)3.(dh/dt)

Make dh/DT subject of formula

dh/dt=(20*3*144)/(25*π*4096) = 8640/321740.8

=

dh/dt= 0.027 ft3/min

In history such as World History? You should be able to distinguish the trends and differences in different periods say "Period 1 vs. Period 2" where each period represents a different range of years (in AP World History I learned it with 6 periods but it varies from year to year of when it is taught)
