Answer:

9/15 = 3/5 (simplified)

Step-by-step explanation:

In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:

$\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$

The adjacent side is the side that makes up the angle but is not the hypotenuse.

I'm assuming the answer box should ask for cos(theta) rather than cos(x).

Write a function rule for the volume of the cylinder shown at the right with a height 3 in more than 4 times the radius of the c

Ludmilka [50]

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the base

h is the height of the cylinder

In this problem

$h=3+4r$

For $r=2\ in$

<u>Find the value of h</u>

$h=3+4*2$

$h=11\ in$

<u>Find the volume of the cylinder</u>

$V=\pi*2^{2}*11$

$V=44*\pi\ in^{3}= 138.2\ in^{3}$

therefore

<u>the answer is</u>

The volume of a cylinder is equal to $138.2\ in^{3}$
