Could someone help me out? A Ferris wheel car moves from point C to point D on the circle shown below: What is the arc length the car traveled, to the nearest hundredth? 8.30 feet 11.30 feet 12.41 feet 13.15 feet
\[\frac{ s }{ \pi d }=\frac{ \theta }{ 180 }\] s = arc length d = diameter Θ = angle
s is what you're trying to find. they gave you d and Θ
alright so.. give me a sec
s/pi35 = 37/180
is that right?
yeah, you did it right, but I made a mistake in the equation I put up. It should be \[\frac{ s }{ \pi d }=\frac{ \theta }{ 360 }\] then \[\frac{ s }{ 35\pi }=\frac{ 37 }{ 360 }\]
oh ok. so what would i do next?
solve for s by mulitplying both sides by 35π
would i first divide 37 by360?
yes you can. It generally doesn't matter whether you do multiplication or division first
37/360=.102 x 35 = 3.597
almost. Don't forget to multiply by the π. You only mulitplied by 35
oh ok 3.597 x 3.14 = 11.29
witch is 11.30 so it would be B right?
yes
Thank you! have a great day!
you're welcome
