Answer:
3/4
Step-by-step explanation:
Tangent is opposite/adjacent
Therefore, 6/8 would be the answer which simplifies to 3/4.
Answer:
A, C and E
Step-by-step explanation:
A. 2.7 > 2.10
C. 6.64 > 6.2
E. 7.4 = 7.40
Thus, The three comparisons that are true is A, C and E

Here, it is helpful to use the formulae for the volume of a cone and a cylinder. I am assuming we are dealing with a right cone and a right cylinder.
![V_{cone}= \frac{1}{3} \pi r^2h](https://tex.z-dn.net/?f=V_%7Bcone%7D%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Cpi%20r%5E2h)
and
![V_{cyl}= \pi r^2h](https://tex.z-dn.net/?f=V_%7Bcyl%7D%3D%20%5Cpi%20r%5E2h)
.
The volumes of both of these figures are equal to 34 cubic inches, as you said. Notice in our formulae, everything is identical EXCEPT that the volume of a cone is basically that of a cylinder divided by three. To reverse this, that is, to find the volume of the cylinder, we would multiply by 3. 34 cubic inches times 3 is
102 cubic inches.
I would like to add that sometimes these formulae seem totally arbitrary. But when you think about the cylinder like a circle with a rolled-up rectangle, you can see that the
![\pi r^2](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E2)
part is the area of a circle, and the height is because it's three dimensional. To translate this into the volume of a cone is a bit trickier. It involves calculus...
![\int\ {x^2} \, dx = \frac{1}{3}x^3](https://tex.z-dn.net/?f=%20%5Cint%5C%20%7Bx%5E2%7D%20%5C%2C%20dx%20%3D%20%20%5Cfrac%7B1%7D%7B3%7Dx%5E3)
. If that looks like nonsense to you, then you can just remember that a cone is kind of a pointy cylinder and must be smaller than a cylinder!
The question ask to choose among the choices that states the truth about the triangle ABC and triangle CDE which is they are similar. The statement that tells the truth is letter C. Triangle ABC is congruent to triangle CDW and also D. Side AC is congruent it side CE. I hope this will help
