How do I find the volume of this?​

Answers

Answer:

(64+320π) cm^3

Step-by-step explanation:

The volume of a cube is the length*width*height, so

the volume of this cube is 4*4*4=64 cm^3

The volume of a cylinder is the base*height

The base of a cylinder is the area of a circle, which is π*the radius of the circle squared

The diameter of the circle base is 16, and the radius is half the diameter, so it is 16/2=8.

The area of the base of the cylinder is π8^2=64π

Now, multiply the base by the height, 5

64π*5=320πcm^3

We now have the volume of the cube and the volume of the cylinder, so now we just add them:

(64+320π) cm^3

If you were to 'unroll' the cylinder you would find the side is actually ALWAYS a rectangle when flattened out?

Answers

Answer:

Yes

Step-by-step explanation:

It's harder to explain but think logically about it or get or get a piece of paper. Then roll it up in as many different ways that u can think of into a cylinder. If u unroll it then I I'll always be a rectangle

I did the quiz and it is B

Step-by-step explanation:

If x) = 4x2 - 16 were shifted 5 units to the right and 2 down, what would the
new equation be?
O A. h(x) = 4(x - 5)2 + 14
B. h(x) = 4(x + 5)2 - 17
C. h(x) = 4(x-18)2 - 5
D. h(x) = 4(x - 5)2 - 18

Answers

Answer:

D

Step-by-step explanation:

To shift h units to the right, replace x with x - h

To shift h units to the left, replace x with x + h.

To shift k units up, add k to the end of the formula for the function.

To shift k units down, subtract k from the end of the formula.

[tex]y=(x+2)^2+6[/tex] is [tex]y=x^2[/tex] shifted left 2 units and up 6 units.

Caution: the right/left shifts sometimes look backwards!

3. The fish tank shown at right needs to be cleaned. The cleaning product instructions state that three drops should be put in the tank for every 140 cubic inches of water. How many drops of cleaner should be used?​

Answers

Drops = 27

First, we need to find the volume of the given tank using the following equation

[tex]Volume = Length*Width*Height\\Volume =14*9*10\\Volume =1260\\[/tex]

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation

[tex]Drops = 3\frac{Volume}{140} \\Drops = 3\frac{1260}{140} \\Drops = 3(9) \\Drops = 27[/tex]
