A cone-shaped hole is drilled into a solid cube of metal as shown. If the cube has sides of length 7 cm, what is the volume of t
aivan3 [116]
This problem really should have the image attached, as we are not quite sure what the radius of the cone is, nor are we sure about how deeply the cone-shaped hole is bored into the cube.  When I did this, I just assumed that the radius of the cone was half the length of the cube which is 3.5, and I assumed that the height of the cone was the same as the height of the cube which is 7. So the volume for the cube itself is 7*7*7=343. Now we have to subtract from that the volume of the cube, which has a formula of V= \frac{1}{3}  \pi  r^{2} h
If we fill in those values I'm assuming to be accurate, our formula then looks like this:
V= \frac{1}{3}(3.14)( 3.5^{2} )(7)
which equals 89.752   If we subtract the volume of the cone from the volume of the cube, we will get that volume of what's left is V=253.2 cm^{3}

The radius is 10 units, and each layer is one unit high. What is the volume of the cylinder in cubed units?​
alexandr1967 [171]

Answer:

Volume of cylinder is 6285.71 square units.

Step-by-step explanation:

Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.

r=10 units

⇒ Diameter, d = 20 units

Also given height is twice its radius.

⇒ Height=2(r)=2(10)=20 units

<h2><em><u>Volume of cylinder=πr^2h</u></em></h2>

= 22/7 × 100×20

=22/7 × 2000

= 44000/7

= 6285.71square units.

hence, volume of cylinder is 6285.71 square units.

picture included , please help, which of the following equations describe the line shown below (1,10) and (-3,2) *check all that
rosijanka [135]
Slope is\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}
Then you use the equation
\text{y=mx+b}
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
10=m(1)+b
You know m (from above) and now you can solve for b.

Rearrange terms:
y-b=mx

And that will be the answer.

Make sense?
