#

what have you tried

#

when solving for arc length, you need two things

#

the central angle, and the radius

#

you already have the radius, but you do not have the central angle yet, which is this

#

#

Yes

#

How would I find the central angle?

#

wait im dumb

#

its already given in the diagram

wait im confused

#

its asking for the measurement of arc EF

lost stone Apr 24, 2024, 3:58 AM

#

yes

zealous steppe Apr 24, 2024, 3:59 AM

#

and the figure says its 13.7m

lost stone Apr 24, 2024, 3:59 AM

#

no thats the length of EF

#

the measure has to be in degrees right

#

?

zealous steppe Apr 24, 2024, 4:00 AM

#

ah shit

#

hold on

#

$arc length = (\frac{\theta}{360})2\pi r$

#

ye i think we gonna use this formula

lost stone Apr 24, 2024, 4:02 AM

#

so 13.7 = (x/360)2pir?

zealous steppe Apr 24, 2024, 4:02 AM

#

given the arc length and radius

#

yep

lost stone Apr 24, 2024, 4:02 AM

#

ok ill try it tysm

#

I got it wow thank u so much for ur help
