Answer:

180 days

Step-by-step explanation:

The formulas for the volume of a cone and a cylinder are ...

V = πr²h . . . . . volume of a cone

V = (1/3)πr²h . . . . . volume of a cylinder

Comparing these formulas, you can see that the 6' high cone at the top will have the same volume as a cylinder of the same radius that is 2' high. So, we can simplify the problem to finding the volume of a cylinder that is 66+2 = 68' high.

V = π(12 ft)²(68 ft) = 9792π ft³ ≈ 30752.5 ft³

When the corn is used at the rate of 170 ft³/day, it will last ...

(30752.5 ft³)/(170 ft³/day) ≈ 180.96 days

The corn will last 180 days.

_____

<em>Additional comment</em>

In scenarios like this, it is inappropriate to round up. There will be about 162 ft³ of corn left after 180 days, which is not enough for an additional day.

Write an expression for 40% of 25

Montano1993 [528]

For this case we must find an expression to find 40% of 25. So, we make a rule of three:

25 -----------> 100%

x -------------> 40%

Where "x" represents the amount that determines 40% of 25.

$x = \frac {40 * 25} {100}\\x = 10$

40% of 25 is 10. And an expression to find it is:

$x = \frac {40 * 25} {100}$

Answer:

$x = \frac {40 * 25} {100}$
