A spherical tank is 4 m tall and therefore has a capacity of about 33500 l (note that 4m is its diameter, and one cubic meter is

1000 l). You have been asked to put level lines on the tank showing the depths where the tank contains 10000, 20000, and 30000 l of liquid.

The level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

<h3>Volume of the spherical tank</h3>

The volume of the spherical tank is calculated by using the following formula as shown below;

V = \frac{4}{3} \pi r^3= \frac{4}{3} \pi (\frac{d}{2} )^3= \frac{4}{3} \pi \frac{d^3}{8} = \frac{1}{6} \pi d^3

<h3>The depth of the tank at different capacity level</h3>

The level lines on the tank showing the depths of different capacities is calculated as follows;

(\frac{1}{6} \pi d^3 )k = V\\\\k = \frac{V}{d^3} \\\\\frac{V_1}{d_1^3} = \frac{V_2}{d_2^3}\\\\d_2 = \sqrt[3]{\frac{V_2d_1^3}{V_1} }\\\\for \ 10,000 \ L\\\\d_2 = \sqrt[3]{\frac{10,000\times 4^3}{33,500} }\\\\d_2 = 2.65 \ m\\\\for \ 20,000 L\\\\d_3 = \sqrt[3]{\frac{20,000\times 4^3}{33,500} }\\\\d_3 = 3.36\ m\\\\d_4 = \sqrt[3]{\frac{30,000\times 4^3}{33,500} }\\\\d_4  = 3.85 \ m

Thus, the level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

<u>Given data :</u><u> </u>

Diameter of tank ( d ) = 4 m

1 cm³ = 1000 l

<h3>Volume of a spherical tank </h3>

The volume of a spherical tank can be calculated as

V = \frac{4}{3}\pi r^3 = \frac{1}{6}\pi d^3

Next step : calculate the level lines at various capacities

applying equation above

V = (\frac{1}{6} \pi d^3)k

where k = v / d³

therefore : di = \sqrt[3]{\frac{Vid^3}{V_{1} } }  ------- ( 1 )

where : di = level line , Vi = volume of tank , V1 = capacity of tank = 33500

             d = diameter of tank

Applying equation ( 1 )

  • For Vi = 10000 l

   level line ( di ) = 2.65 m

  • For Vi = 20000 l

 level line ( di ) = 3.36 m

  • For Vi = 30000 l

  level line ( di ) = 3.85 m

Hence we can conclude that The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

Norma-Jean [14]

Answer:

angle F would be 64 degrees

Explanation:

cause 74 +77+70+39+36= 296 then do 360-296 and you'll get 64 just remember it always has to equal 360 degrees

Why is it important to distress?
Anna35 [415]
I agree with the person above.
Prolonged stressing causes mental illnesses such as depression, anxiety, and personality disorders.
It causes physical illnesses such as cardiovascular disease, high blood pressure, abnormal heart rhythms, heart attacks, heart disease, and strokes.

Ways to distress are things like exercising, eating healthy, meditate, take a deep breath in and out, and find a hobby that helps you distress. Also I would full heartedly recommend watching Bob Ross.

Patrick drives from p to q at an average speed of 40mph.
Bumek [7]

The distance in miles from P to Q is 12 miles

<h3>Distances and speed</h3>

Let the distance from P to Q be "d"

Since the formula for calculating speed is expressed as:

  • s =d/t

For the distance of P to Q

40 = d/t

d = 40t

If he drives back at an average speed of 45mph and 2 mintes less, then;

45 = d/t - 0.033

d = 45 (t - 0.033)

Equating both distances

40t = 45(t - 0.033)

40t = 45t - 1.485

-5t = -1.485
t = 0.297

Get the distance from P to Q:

d = 40(0.297)
d = 11.88 miles

Hence the distance in miles from P to Q is 12 miles
