a mailing tube in the shape of cylinder has a height of 24 inches and a radius of 3 inches. what is the volume, in cubic inches,
TiliK225 [7]

ANSWER

The volume of the mailing tube is 678.6 square inches to the nearest tenth.

EXPLANATION

The volume of a cylinder is calculated using the formula;

V=\pi \:  {r}^{2} h

Since the mailing tube is in the form of a cylinder, we use this formula to find its volume.

We substitute h=24 and r=3 to obtain,

V=\pi \times {3}^{2} \times 24

V=216\pi  {in}^{2}

V=678.6{in}^{2}

There is a mound of g pounds of gravel in a quarry. Throughout the day, 300 pounds of gravel are added to the mound. Two orders
galina1969 [7]

Answer:

g+300-700-700=1500, g=2600

Step-by-step explanation:

At the start of the day there are g pounds of gravel in the quarry.

Then it says that there were 300 pounds added to the mound, so at this point the pounds of gravel in the mound are now g+300.

Then two orders of 700 pounds are sold and removed from the mound. That means they removed 700 pounds from the mound 2 times. Therefore at this point the pounds of gravel in the mound are now g+300-700-700.

Then it says that at this point, the amount of pounds in the mound are 1500.  Hence we get

g+300-700-700=1500

To solve for g we just add 700 two times to both sides of the equation, and subtract 300 from both sides of the equation, getting:

g+300-700-700+700+700-300=1500+700+700-300

And so g=2600

A line has a zero slope and passes through the point (-5,4). What is the equation of the line?
zhenek [66]

Answer:

y=4

Step-by-step explanation:The answer is y=4 because the line has no slope so it will not increase or decrease at a constant rate. If we were to plug it in it would be y=0/0+4. this basically means that the y-axis is equivalent to 0/0 (no slope) plus 4, we can then cancel out 0 since it is nothing simplifying the equation to y=4.
