OpenStudy (anonymous):

Is this correct?

jimthompson5910 (jim_thompson5910):

is what correct? I don't see your work on this one

jimthompson5910 (jim_thompson5910):

oh nvm

jimthompson5910 (jim_thompson5910):

I see it on the screenshot

OpenStudy (anonymous):

I did 36/360x2xPIx10

jimthompson5910 (jim_thompson5910):

you are 100% correct, nice job

OpenStudy (anonymous):

uh how about this one?

OpenStudy (anonymous):

OpenStudy (anonymous):

20/2?

OpenStudy (anonymous):

10 right

jimthompson5910 (jim_thompson5910):

yep, just cut it in half (semi means half)

OpenStudy (anonymous):

To find arc length what do you need to multiply a circle's circumference by?

jimthompson5910 (jim_thompson5910):

you tell me

jimthompson5910 (jim_thompson5910):

you did it earlier above in this same post

OpenStudy (anonymous):

multiply radius by the fraction of the circle covered by the arc

jimthompson5910 (jim_thompson5910):

you wrote 36/360x2xPIx10 remember?

jimthompson5910 (jim_thompson5910):

this portion here "2xPIx10" is the circumference of the circle with a radius of 10

OpenStudy (anonymous):

the fraction of pi covered by the arc?

jimthompson5910 (jim_thompson5910):

so the basic format is (angle/360)*Circumference

jimthompson5910 (jim_thompson5910):

yes pretty much

OpenStudy (anonymous):

WAit the first one i mean multiply pi by the fraction of the circle by the arc

jimthompson5910 (jim_thompson5910):

I would go with the angle because that's more descriptive

OpenStudy (anonymous):

so is it multiply pi by the fraction of the circle covered by the arc?

jimthompson5910 (jim_thompson5910):

what are all of your answer choices

OpenStudy (anonymous):

a fraction of the radius multiply pi by the fraction of the cirle covered by the arc the fraction of pi covered by the arc the fraction of the circle covered by the arc

jimthompson5910 (jim_thompson5910):

hmm d sounds like the most accurate, but it's not what I would say if I were answering it

jimthompson5910 (jim_thompson5910):

I would say "the fraction of the angle over 360" or something like that

OpenStudy (anonymous):

tricky question

jimthompson5910 (jim_thompson5910):

yeah

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

it's not C

jimthompson5910 (jim_thompson5910):

that statement doesn't make much sense
