How many liters does the 9 meter long tank hold if its diameter is 2.5 meters? answer quickly please ​

9514 1404 393

  44,178.6 L

Step-by-step explanation:

The volume in liters is conveniently computed using dimensions in decimeters (dm). There are 10 of those in each meter, so the dimensions are ...

  90 dm long by 25 dm in diameter

In terms of diameter, the volume of a cylinder is ...

  V = (π/4)d²h

  V = (π/4)(25 dm)²(90 dm) = 14062.5π dm³ . . . . 1 dm³ = 1 L

Using the "pi button", we find the volume to be ...

  V = 14062.5(3.141593) L = 44,178.6 L

If you inappropriately use 3.14 for pi, your volume will be 44,156.25 L.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
