Question

Use the arc length formula and the given information to find r.
s = 12 cm, θ = 36°; r = ?

Answer 1

what's the formula?

Answer 2

i know that s=r*q

Answer 3

and that q=s/r

Answer 4

but how do i find r?

Answer 5

you mean instead of Q, u meant theta?

Answer 6

give me a sec i'll figure this out

Answer 7

s = r theta
to find r you do s/theta
which is 12/ 36 degrees

Answer 8

what's the answer of the question?
do u have it?

Answer 9

would it be 1/3?

Answer 10

yes

Answer 11

thank you

Answer 12

nws :)

Answer 13

glad i could help :)

Answer 14

Hate to throw cold water on you two, but in discussions of arc length in a circle, we MUST express the angle, theta, in radians.

Answer 15

36 degrees can be converted to radians as follows:

36 degrees Pi radians
---------- * --------------
1 180 degrees
