Water flows at a rate of 6000 cubic inches per minute into a cylindrical tank. The tank has a diameter of 180 inches and a height of 72 inches. What is the height, in inches, of the water in the tank after 5 minutes? Round your answer to the nearest tenth.

Respuesta :

The height of water in tank after 5 minutes is 1.2 inches

Solution:

Water flows at a rate of 6000 cubic inches per minute into a cylindrical tank

Therefore,

1 minute = 6000 cubic inches

Therefore, for 5 minutes, rate is given as:

5 minute = 5 x 6000 = 30000 cubic inches

The tank has a diameter of 180 inches and a height of 72 inches

Diameter = 180 inches

[tex]Radius = \frac{diameter}{2} = \frac{180}{2} = 90[/tex]

Thus, radius = 90 inches

We know that, volume of the water filled in the cylindrical tank in 5 minutes is 30000 cubic inches

Volume of cylinder is given as:

[tex]v = \pi r^2 h[/tex]

Where, "r" is the radius and "h" is the height of tank

[tex]30000 = 3.14 \times (90)^2 \times h\\\\30000 = 25434 \times h\\\\h = \frac{30000}{25434}\\\\h = 1.179 \approx 1.2[/tex]

Thus height of water in tank after 5 minutes is 1.2 inches
