Answer 1

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?

7.91 feet

8.32 feet

10.99 feet

11.89 feet

Answer 2

Can you convert 42 degrees into radians ?

Answer 3

if you tell me how i can because i don't know how

Answer 4

\(\Large \pi^r = 180^o \\ so, \\ \Large x^r= x^o \times \dfrac{\pi}{180}\)

Answer 5

here
x = 42

Answer 6

okay so i do x degree 42/180?

Answer 7

or 42 * x/180

Answer 8

\(\Large x^r= 42 \times \dfrac{\pi}{180} =...\)

Answer 9

i don't know how to do this can you teach me

Answer 10

to convert degree angle in to radians, just multiply it by pi/180


so 42 degrees = 42*pi/180 radians
you can use calculator to find the decimal value or keep it as is

Answer 11

then you need, arc length,
Arc length is just \(\Large r \theta \)

theta is angle in radians which is 42pi/180
and r is the radius = diamerter/2 = 30/2 =15

Arc length = 15*42pi/180 = ... (use calculator)

see if you get this...

Answer 12

10.99?

Answer 13

yep, thats correct arc length... :)
rounded to 11

Answer 14

so the answer is 10.99 and if you round its 11

Answer 15

yup

Answer 16

thanks

Answer 17

welcome ^_^
