Answer 1

@Loser66

Answer 2

@Vivid, sorry to disappoint you, but not even close.

Answer 3

@Hero This isn't my expertise. Your better at this than me. Your smart!

Answer 4

I really need your help @Hero

Answer 5

Start with this formula: \(s = r\theta\)

Answer 6

Convert 72 degrees to radians

Answer 7

1.256

Answer 8

or 0.4pi?

Answer 9

Try to keep it in exact format since your answers are in exact format

\(72^{\circ} = \dfrac{2\pi}{5}\)

Answer 10

radians

Answer 11

omg it makes a bit of sense now. Is 2 hard?

Answer 12

It's only as hard as you believe it to be. In reality, none of it is hard.

Answer 13

whats the step I should ask.

Answer 14

you are right about that ^

Answer 15

For the second one, they're basically giving it to you. All you have to do is just plug and play.

Answer 16

Actually, for the 1st problem did you calculate the Arc Length, S?

Answer 17

it would be 2pi/5?

Answer 18

You were supposed to use this formula:

\(S = r\theta\) to calculate the Arc Length. You need to multiply \(\theta = \frac{2\pi}{5}\) by the radius of the wheel. You should review Arc Length of a circle concepts.

Answer 19

would it be, 72/360 *18pi

Answer 20

idk what that is simplified

Answer 21

72/360 =0.2

Answer 22

You could use a tutor.

@chmvijay

Answer 25

Soconfusedddd

Answer 26

idk why my pciture got deleted.

Answer 27

does this make sense? @mathmale

Answer 28

Chaser: Hello!
Unfortunately I cannot spend more than a minute or two here, because I have to leave the house for a dental appointment.
First: Hero has done a very good job of explaining his material. To understand this material, you're going to have to get involved as best you can, instead of just saying that you're "confused.
I'd suggest you go through what Hero has typewritten to you and make up a review page (or paragraph) about arc length and about conversion from radians to degrees and degrees to radians. Then, if you still feel confused, ask some questions. That would involve you in this problem solving.
I will look for your response later, but for now, as I said, i have a dentist appointment to worry about.

Answer 29

Thank you!
