A factory wants to fill a conical storage tank with sand. The tank has a height of 19.5 meters and a diameter of 30.7 meters
taurus [48]

9514 1404 393

Answer:

  4,811.49 m³

Step-by-step explanation:

The volume of a cone is computed using the formula ...

  V = (1/3)πr²h

Using the given numbers, we find the volume to be ...

  V = (1/3)π(15.35 m)²(19.5 m) = 1531.54625π m³ ≈ 4,811.49 m³

_____

<em>Additional comment</em>

If you inappropriately use 3.14 for π, you get a volume of 4809.06 m³. That 3-digit value is inappropriate because a value accurate to 6 significant figures or more is needed to support an answer accurate to 6 significant figures.

A number x is no more than 9 units away from 8. Write and solve an absolute-value inequality to show the range of possible value
Montano1993 [528]
The answer is a (|x - 8| ≤ 9 and -1 ≤ x ≤ 17) Because the difference between x and 8 can't be greater than 9, but it can be less than or equal to it, and because the range that x could be would be -1 to 17, since 8 + 9 = 17 and 8 - 9 = -1.

Whats 11+​(-​3)-1/8 j-3/8 j+7 ?<br><br> Thanks in advance!
Anuta_ua [19.1K]

Answer:

Your answer is

=-\frac{j}{2}+15

Step-by-step explanation:

11+​(-​3)-1/8 j-3/8 j+7

=11+\left(-3\right)-\frac{1}{8}j-\frac{3}{8}j+7\\

=11-3-\frac{1}{8}j-\frac{3}{8}j+7

add the similar objects

=11-3-\frac{1}{2}j+7

=\frac{1}{2}j=\frac{j}{2}

=11-3-\frac{j}{2}+7

=-\frac{j}{2}+15
