GUYS I NEED HELP ASAP!!!<br><br> Help me solve ?
Shalnov [3]

Solution:

$h=\frac{ A-2\pi r^2}{2\pi r }

Given data:

A=2\pi r^2+2\pi r h

Let us determine what is h using given A.

A=2\pi r^2+2\pi r h

Subtract 2\pi r^2 on both sides of the expression.

⇒ A-2\pi r^2=2\pi r^2+2\pi r h-2\pi r^2

⇒ A-2\pi r^2=2\pi r^2-2\pi r^2+2\pi r h

⇒ A-2\pi r^2=2\pi r h

Divide both sides of the expression by 2\pi r.

$\frac{ A-2\pi r^2}{2\pi r }=\frac{2\pi rh }{2\pi r }

$\frac{ A-2\pi r^2}{2\pi r }=h

$h=\frac{ A-2\pi r^2}{2\pi r }

Option C is the correct answer.

Hence $h=\frac{ A-2\pi r^2}{2\pi r }.

Maksim231197 [3]

Answer:

Step-by-step explanation:

I don't exactly know what the problem is asking.

4+3+2=9

Sooo, there are 9 different songs.

You then have to divide 360 by 9 to figure out how many times each song is going to play.

360/9= 40

Each song is going to play 40 times.

I hope that's the answer to the question. If it isn't, this will probably get you closer to the answer.

Good luck! :D
