To find the volume of a cylinder you would multiply pi, radius squared, and height.

r= 6 ft
h= 2 ft
pi= 3.14

First you want to square your radius, so you would do 6 times 6.

This gives you 36.

Now you just multiply by 3.14 and get 113.04, then multiply that by 2.

Your final answer is 226.08ft³

If you need further explanation, just let me know! :)

3. Is XY Tangent to circle Z?<br> Y<br> 12 X<br> (20<br> Z<br> 18

Ratling [72]

Answer:

XY is a tangent

Step-by-step explanation:

Given

$XY = 12$

$WY = 20$

$WZ = 8$

Required

Is XY a tangent?

XY is a tangent if:

$WY^2 = XY^2 + WX^2$

Because XY should make a right angle at point X with the circle

Where

$WX = 2 * WZ$

So, we have:

$WY^2 = XY^2 + WX^2$

$WY^2 = XY^2 + (2*WZ)^2$

$WY^2 = XY^2 + (2WZ)^2$

$WY^2 = XY^2 + 4WZ^2$

This gives:

$20^2 = 12^2 + 4*8^2$

$400 = 144 + 256$

$400 = 400$

<em>Yes, XY is a tangent</em>

Identify which of the following is not equivalent to 2 3/4.

mezya [45]

The figure that is not equivalent to 2¾ is 2¼ × 2½. That is option B.

<h3>Simplification of equivalent fractions</h3>

Simplification is a process that is used to make a fraction appear in its simplest forms.

The fraction given is = 2¾

The simplification of the fraction= 2^3/4 = 2

But simplification of 2¼ × 2½ is equal to;

2¼= 0.5

2½= 1

Therefore 2¾ is not equivalent to 2¼ × 2½ when simplified.

In the diagram below of right triangle ACB, altitude CD is drawn by hypotenuse AB. if AB= 36 and AC= 12, what is the length of A

Nady [450]

36 squared + 12 squared = AD squared
1296 + 144 = AD squared
square root of 1440 = AD
