Answer:

x = -9

Step-by-step explanation:

- 2(x + 7) = 4

Distribute

-2x -14 = 4

Add 14 to each side

-2x-14+14 = 4+14

A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet of grain can the bin hold

dimaraw [331]

Answer:

1225π

Step-by-step explanation:

The question concerns the volume of the cylinder.

The formula of the volume is:

$V=\pi r^{2} h$ , where r is the radius and h is the height.

Plugging the given numbers into the formula, we find that:

$V=\pi * 49 * 25=1225\pi$

The result - 1225π shows that the cylinder can be filled fully with that given amount.
