If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter, what is the vo
Alik [6]
The formula for the volume of a cylinder is \pi  r^{2} h

We know the diameter, so we can easily find the radius.  The diameter is twice as long as the radius, so we divide the diameter by 2 to find the radius.  This is equal to 6/2 = 3.  Now, we plug our numbers into the formula.

\pi * 3^{2} *3= \pi *9*3=27 \pi m^{3}

This could also be written: 84.82  m^{3}

Both 27 pi cubic meters and 84.82 cubic meters are correct answers, so choose whichever one you think your teacher would prefer.

EleoNora [17]

Answer:

\large\boxed{-\dfrac{7}{5}}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, 11) and (7, 4).

Substitute:

m=\dfrac{4-11}{7-2}=\dfrac{-7}{5}=-\dfrac{7}{5}
