Answer:

1069.8 m^{3} for 3.14 as pi (go with this one if you aren't sure!)

1070.4 m^{3} for 3.14159265359 as pi

Step-by-step explanation:

The formula for a cyliner's volume is \pi *  radius^{2} * height.

3.14* 7.8^{2} * 5.6

3.14 * 60.84 * 5.6=

1069.81056

D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(1,-2)(10.-4)

d = sqrt (10 - 1)^2 + (-4 - (-2)^2
d = sqrt (9^2 + (-4 + 2)^2
d = sqrt (9^2 + (-2^2)
d = sqrt (81 + 4)
d = sqrt 85
d = 9.2

An upright cylinderical tank with radius 7 m is being filled with water at a rate of 2 m^3/min. How fast is the height of the wa
cricket20 [7]

Answer:

0.0130 m per min. to  4 decimal places.

Step-by-step explanation:

If  2 m^3 of water is added we have volume = 2 = π 7^2 h   where h is the height:

h = 2 / (π 7^2) =  0.01299 m.

The correct question in the attached figure

we know that

applying the law of sines
g/sinG=k/sinK

g=3 units
G=30°
k=4 units
K=?
so
g/sinG=k/sinK------> g*sinK=k*sinG-----> sinK=k*sinG/g
sinK=4*sin 30°/3-----> 2/3
K=arc sin(2/3)-------> K=41.81°

case 1)
for angle K=41.81°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+41.81)--------> H=108.19°

h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 108.19°/sin 30°
h=5.70 units

case 2)
for angle K=180°-41.81°---------> K=138.19°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+138.19)--------> H=11.81°

h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 11.81°/sin 30°
h=1.2 units

therefore

the answer is the option
<span>A. 1.2 or 5.7</span>

<h3>Solution:</h3>

<u>Given:</u>

  • ∠A = 50°

<u>In the diagram given, we can tell that:</u>

  • ∠A and ∠B are a linear pair.
  • ∠B and ∠C are a linear pair.

<u>This means that:</u>

  • ∠A + ∠B = 180°
  • ∠B + ∠C = 180°

<u>Step-1: Find ∠B.</u>

  • ∠A + ∠B = 180°
  • => 50 + ∠B = 180°
  • => ∠B = 180 - 50
  • => ∠B = 130°

<u>Step-2: Find ∠C.</u>

  • ∠A = ∠C (Vertically opposite angles
  • => ∠C = 50°

<u />
