Answer:

  • 1.91 m

Step-by-step explanation:

<u>The volume of water collected:</u>

  • V = lwh
  • V = 6 m * 4m * 1 cm = 600* 400* 1 cm³ = 240000 cm³

<u>Volume of cylinder:</u>

  • V = πr²h

<u>We have the values of V and r, find the value of h:</u>

  • h = V/πr²
  • h = 240000 /(3.14*20²) = 191 cm = 1.91 m

\large\pink{\sf{Given:-}}

  • Length = 6m
  • Width = 4m
  • Height = 1cm
  • Internal Radius of cylinder = 20 cm

\large\purple{\sf{Solution:-}}

\tt \: volume = length \times width \times height

\tt \: volume = 6 \times 4 \times  1

\tt \: volume = 24m ^{3}

<h3>Volume of water in cylindrical vessel;</h3>

\sf\pi \: r ^{2} h

  • r = 20
  • h = ?
  • π = 22/7

\sf \: h =  \frac{volume}{\pi r^{2} }

\sf \: h =  \frac{24 \times 7}{22 \times 20 \times 20}

\sf \: h = 0.190 \: cm

<em>Therefore, The height of cylinder will be 0.190 I'm approximately...</em>

Please solve the table correctly.
Hitman42 [59]

Answer:

See below.

Step-by-step explanation:

No. Triangles       Perimeter

 1                                  14

2                                  18

3                                  22

We see from the table, after the first  perimeter  (= 14),  with  each increase of 1 in the number of triangles,  the perimeter increases by 4.

As an equation it is  P = 14 + 4(n - 1)  where P = perimeter and n = number of triangles.

PLEASE HELP FAST ILL MARK YOU BRAINLYEST
Alborosie

Answer:

look at explanation (I go down the first column of scenarios and then move on to the right column)

Step-by-step explanation:

1) The first one will be same as original because the decrease and increase are the same, and happen right after each other so you get the same amount

2) Second one you get greater than original. You're doubling the initial value, and then decreasing by a smaller percentage, so you still get greater than your initial value

3) Third you get greater than original. You're adding 50% of the initial value, and decreasing by 33.5% of the new value, which will still give you more than the original

4) Fourth, you get greater than original. You're adding 60% of the initial value, and then decreasing by 40% of the new value, which will still give you greater than the initial value

5) Fifth you get less than the original. You're decreasing by 75%, and then adding 50% of the new value, which still gives you less than the initial value
