Answer:

653.45 cm^2

Step-by-step explanation:

The volume of a cylinder can be found using:

v=pi r^2 h

We know the radius is 4, and the height is 13, so we can substitute them in

v=pi (4^2)(13)

v=pi (16)(13)

v=pi 208

v=653.451272

Rounded to the nearest hundredth

v=653.45

So the volume is 653.45 cm^3

Answer: The volume of the cylinder is 653.45 cm^3

Step-by-step explanation:

-To figure out the volume of the cylinder, you need to the have the formula:

V=\pi r^{2} h

-Set the radius and the height to the equation:

V=\pi × 4^2 × 13

-Solve:

V=\pi × 4^2 × 13

= \pi × 16 × 13

= \pi × 208

=653.451

-Round up to the nearest hundredth:

= 653.45

At Alan's auto shop, it takes him minutes to do an oil change and minutes to do a tire change. Let be the number of oil changes
kirill [66]

Complete question :

At Alan's auto shop, it takes him 9 minutes to do an oil change and 12 minutes to do a tire change. Let x be the number of oil changes he does. Let y be the number of tire changes he does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Alan can do in less than an hour ( minutes).

Answer:

9x + 12y < 120

Step-by-step explanation:

Given that:

Time taken for oil change = 9 minutes

Time taken for tire change = 12 minutes

x = number of oil changes ; y = number of tire changes

Total hours = 1 hour = 60 minutes

Number of oil and Tyre changes possible in less than an hour

(Number of oil changes * time taken) + (number of tire changes * time taken) less than 60 minutes

9x + 12y < 120

What is the ratio for sine
Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is \frac{\text{opposite}}{\text{hypotenuse}}

cosine is \frac{\text{adjacent}}{\text{hypotenuse}}

tangent is \frac{\text{opposite}}{\text{adjacent}}

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent
