Question

Find each arc length. Round to the nearest hundredth.

Answer 1

So we first have to find the degree measure of it, get that over 360s, get the circumference of the circle, and get the arc length e.e

So first find the degree measure of MKL

Answer 2

We know that MKL is a straight line plus KL
So what is KL
Remember that KL + KJ = 90

Answer 3

90 or 270

Answer 4

...
JL is 90 degrees, JK is 52 degrees, what is KL

Answer 5

JL = JK + KL
JL = 90
JK = 52
What is KL

Answer 6

142

Answer 7

...

Answer 8

Plug the values of JL and JK into JL = JK + KL find KL e.e

Answer 9

look at the diagram---

Answer 10

im lost

Answer 11

What grade are you in?

Answer 12

11th

Answer 13

Then you should know how to plug in values

Answer 14

you say that KL and KJ = 90

Answer 15

... I say JL = JK + KL

Answer 16

no before this

when did i say they were 90 degrees each

Answer 18

104?

Answer 19

...bro.... you're in 11th grade, do you now know how to find x when you have an equation?..... simple subtraction...

Answer 20

Literally put the values in
you have that JL = 90 JK =52
So put those into JL = JK +KL, and find kl

Answer 21

38

Answer 22

yay
So how many degrees is MKL in all, remember that it's a straight line plus that angle, and a straight line is 180 degrees

Answer 23

218?

Answer 24

Yes so remember that this is 218 degrees

Now we need the circumference of the circle
do you know how to solve for circumference?

Answer 25

2 pie 10 and 214 divide by 360?

Answer 26

...no
10 is diameter, and circumference is 2pi r

Answer 27

now i just need to find r

Answer 28

...
did you know that radius is half of diameter?

Answer 29

5

Answer 30

So we have 2 pi r
So the circumference is 10pi, agreed?

Answer 31

yes

Answer 32

So we have
218 degrees out of 360 degrees, and x meters out of 10pi meters\[\frac{ 218 }{ 360 } = \frac{ x }{ 10\pi }\] cross multiply and then find x

Answer 33

Do you know how to do that?

Answer 34

360? its been a minute since i did cross multiply

Answer 35

...
Do you know what cross multiplication is?

Answer 36

yes

Answer 37

So do it, multiply, and then find x

Answer 38

\[\frac{ a }{ b } = \frac{ c }{ d } \] \[bc=ad\]

Answer 39

6.05?

Answer 40

...
may i ask, how'd you get that? write out what you did...

Answer 41

bc = 360x and ad i got 2180

Answer 42

Where'd you get the 2180 from

Answer 43

when i multiple 218 with 10 pi

Answer 44

10pi times 218...

Answer 45

So then that equals 360x...
And then divide ^^^^^ by 360
i gtg sorry
