The volume of a cylinder is given by the formula V= πr^2h, where r is the radius of the cylinder and h is the height. Suppose a

11111nata11111 [884]

we know that

The volume of a cylinder is given by the formula

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

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

$r=x+8\\ h=2x+3$

Substitute the values in the formula above

$V=\pi*(x+8)^{2}*(2x+3)$

$V=\pi*(x^{2}+16x+64)*(2x+3) \\ V=\pi *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=\pi *(2x^{3} +35x^{2} +176x+192)$

therefore

the answer is

The volume of the can is equal to

$V=\pi *(2x^{3} +35x^{2} +176x+192) units ^{3}$

How do you multiply positive and negative integers?

Andrej [43]

-- Ignore the signs and multiply the numbers.

-- If the original two numbers have the same sign, then the product is positive.

-- If the original two numbers have different signs, then the product is negative.

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she ha

Setler [38]

Answer:

Let's define the variable x as the number of apples in each bag.

We know that she bought 4 bags, then the total number of apples that she has is:

Apples = 4*x

Now she eats one apple for each bag, then she eats 4 apples, so she now has:

Apples = 4*x - 4

And we know that this is equal to 28, then:

4*x - 4 = 28

now we can solve this for x.

4*x = 28 + 4 = 32

x = 32/4 = 8

x = 8

There are 8 apples in each bag.

For the diagram part, by a small online search y found the image that you can see below.

The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.
