Answer:

45.8 cm

Step-by-step explanation:

The volume of a metal cylindrical rod is 126 cubic meters. ​The radius is 6 m. ​ ​What is the height of the rod in millimeters?
Dahasolnce [82]

Answer:

1.11 mm

Step-by-step explanation:

The height of a cylinder can be found using the formula: h=V/(πr^2)

This formula was found by taking the formula for the volume of a cylinder and solving for h, or height. Knowing that V is 126 and the radius is 6, we can plug in our known variables in order to solve for h.

Solve the following questions-
Setler79 [48]

Answer:

  2/5

Step-by-step explanation:

To get the ratio as a pure number, it must be expressed as the quotient of two values that have the same units. For the purpose here, it is convenient to convert both values to units of seconds.

__

<h3>units conversion</h3>

The conversion factor between minutes and seconds is ...

  1 minute = 60 seconds

Multiplying this equation by 3 gives ...

  3 minutes = 180 seconds

__

<h3>ratio of interest</h3>

Then the desired ratio is ...

  (72 seconds)/(3 minutes) = (72 seconds)/(180 seconds) = 72/180

  = (36×2)/(36×5)

  = 2/5

The ratio in its simplest form is 2/5.

Can someone pls help me answer this :/​
eimsori [14]

Answer:

y = - \frac{3}{2} x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = \frac{0-6}{4-0} = \frac{-6}{4} = - \frac{3}{2}

Since the line crosses the y- axis at (0, 6) ⇒ b = 6

y = - \frac{3}{2} x + 6 ← equation of line
