Margaret [11]3 years ago

Answer:

The volume of the cylinder is 3 times the volume of the cone

Step-by-step explanation:

The formula for the volume of the cylinder is given by :

V_{cy}=\pi r^2 h .....(1)

Where

r and h are the radius and the height of the cylinder

The formula for the volume of the cone is given by :

V_{cone}=\dfrac{1}{3}\pi r^2h ...(2)

From equation (1) and (2),

\dfrac{V_{cy}}{V_{cone}}=\dfrac{\pi r^2 h}{\dfrac{1}{3}\pi r^2 h}\\\\=3\\\\V_{cy}=3\times V_{cone}

So, the volume of the cylinder is 3 times the volume of the cone.

Given (21,7) and (x,<br> 1), find all x such that the distance between these two points is 17.
Dmitriy789 [7]

Answer:

21+/-sqrt(253)=x

So one value for x is 21+sqrt(253)

and another is 21-sqrt(253)

Problem:

Given (21,7) and (x,1), find all x such that the distance between these two points is 17.

Step-by-step explanation:

Change in x is x-21

Change in y is 7-1=6

distance^2=(change in x)^2+(change in y)^2

17^2=(x-21)^2+(6)^2

289=(x-21)^2+36

Subtract 36 on both sides:

289-36=(x-21)^2

253=(x-21)^2

Take square root of both sides:

+/-sqrt(253)=x-21

Add 21 on both sides:

21+/-sqrt(253)=x

What is the volume of a rectangular prism with length 12 in., height 16 in., and width 13 in.? V+lwh. _______in3
Verizon [17]
Hello!

To find the Volume, you'll need to multiply all of the measurements together. So you'll need to multiply 12, 16, and 13 together to get the Volume. First, let's multiply 12 and 16 together to get 192

192*13

Now you're left with 192*13. After you've multiplied them together you should get 2496

You should now have a Volume of 2496in³

I hope this helps!
