A cone has a height of 4 in and a radius of 6 in. What is the volume of the cone?
8π in3
24π in3
48π in3
144π in3

Answers

Answer 1

Answer:

48π in³

Step-by-step explanation:

[tex]V=\frac{1}{3} \pi r^2h[/tex]

Plug in the radius 6 in and the height 4 in

[tex]V=\frac{1}{3} \pi (6)^2(4)\\V=\frac{1}{3} \pi (36)(4)\\V=\frac{1}{3} \pi (144)\\V=48\pi[/tex]

Therefore, the volume of the cone is 48π in³.

I hope this helps!

What is scatter plot?

Using Cartesian coordinates, a scatter plot (also known as a scatterplot, scattergraph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that shows the values of typically two variables for a set of data. One more variable can be shown if the points are coded (by color, shape, or size).

i need help please im lost on this question

Answers

Answer:

30 inches

Step-by-step explanation:

You have to work backwards. Take 565.2 and divide by 6. You get 94.2. You then divide that by pi or 3.14 and get 30. If you went the other way, 565.2 divided by 3.14 you would get 180. 180 divided by 6 is still 30.

Answer:

h = 5in

Step-by-step explanation:

So for this problem you kinda have to work backwords.

You would use the formula for finding the volume of a cylinder, except you are not finding you are finding the height.

volume of cylinder formula: V=π r² h

Start by plugging everything in:

565.2 = (3.14)(6²)(h)

565.2 = (3.14)(36)(h)

565.2 = (113.04)(h)

to slove for h you would need to get the varible alone, meaning you divide everything by 113.04.

h = 5in

4. One cubic inch of sand weighs about 1 ounce. Find the weight of the treasure chest (in pounds) after it is filled with sand. Assume that the chest weighs 20 pounds when empty.
*There are 16 ounces in a pound

Answers

Answer:

2.  7

4. 60

Step-by-step explanation:

1. The base of the treasure chest is the bottom edge
Because most chests are rectangles, we can assume that the base is also a rectangle
This means that the perimeter would be 3+3+2+2, which is 10 ft


2.
To find the area of the chest’s base, you must multiply 3 by 2

3*2 is 6, so the answer is 6 feet squared

3.
I’m not completely sure what this question is asking, but I’ll do my best

It looks like it is asking if you can find the surface area by multiplying the base by one of the side lengths (again, not sure which one because it’s not labeled)

This wouldn’t work regardless of the side length, however, because base times height is equal to the volume of the chest and not the surface area


4. To do this, it would be easier to find how much sand can fit in the chest, and then do weight after you have that figure

There are 12 inches in a foot, so the measurements of how much sand can fit in the chest could be found by multiplying 12 by the side length
This would leave you with measurements of 36, 24 and 24
Volume is base * height, so first multiply the two base measurements (36 and 24)
This leaves you with 624
Multiply that by height (24) and you get 14,976 cubic inches of sand

Because each cubic inch of sand weighs about 1 ounce, we know that the weight of the sand is 14,976 ounces

To find out how much that is in pounds, divide 14,976 by 16

This leaves you with 936 lbs
Add the additional 20 that comes from the chest and you get 956 lbs total
The chest weighs 956 pounds when filled with sand

Hope that helped!

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth

Answers

Answer:

V = Π (4)2*12

V = 603.19 cm3

Step-by-step explanation:

A soup can is a cylinder.

The formula for volume of a cylinder is the following: V= Πr2h.

 

We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).  

The formula asks for radius so we divide the diameter by 2.  

r =8/2 = 4.

Now we can just plug the numbers into the formula

 

V = Π (4)2*12

V = 603.19 cm3

 

Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

V = Π (4)2*12
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.

We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula

V = Π (4)2*12
V = 603.19 cm3

Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

Step 2: Subtract 8q from both sides

Now your equation is 7q - 16 = 12

Step 3: Add 16 to both sides

Now the equation is 7q = 28
