Question

g

Answer 1

s = theta * r
so on the first one
s = pi/4 * 14 = 7pi/2

Answer 2

make sense?

Answer 3

s = arclength = theta*r

Answer 4

@MayMay_69 ?

Answer 5

Nope I have no clue what you just wrote up there

Answer 6

what is the angle in the first one?

Answer 7

hello?

Answer 8

\(\bf \textit{s = arc's length = } \Large \cfrac{\theta r \pi}{180}\)

Answer 9

which is pretty much what zzr0ck3r said :/

Answer 10

@MayMay_69 look at the first one...what is the angle? you are given this information you should be able to answer that at least...

Answer 11

what is that in radians?

Answer 12

no what is 45 degrees in radians?

Answer 13

180 = pi

Answer 14

45 = ?

Answer 15

I am

Answer 16

ok then you need to learn how to convert degrees into radians
radians = degrees * (pi/180)
so you have
radians = 45*pi/180 = ?

Answer 17

ok arclength = angle * radius (angle must be in radians)

for the first one
the angle is 45 degrees but we want it in radians
radians = 45*pi/180 = pi/4
so our angle in radians is pi/4
now we simply multiply that by the radius.
14*pi/4 = 7pi/2
does this make sense?

Answer 18

hello?

Answer 19

ahh ok sorry

Answer 20

that's fine, you can

Answer 21

its best to not simplify, just leave pi as pi. 3.14 is an approximation

Answer 22

it seems you need to gi back and study some of the early stuff

Answer 23

you need to learn about radians and degrees more.

Answer 24

so no time to study them today, these assigments are referring to degrees and radians already, so the material has been covered by now

if you're given exercises today that include radians and degrees
what makes you think the upcoming material is going to skip them?

so if you don't have the time for the material to be learned, I don't see any point to any of these exercises
