Question

What is the arc length if Θ = 6 pi over 5 and the radius is 2 cm?

3 pi over 10

24 pi over 5

5 pi over 12

12 pi over 5

Answer 1

12pi/5
ithink?

Answer 2

s=theta*radius
s=arc length

Answer 3

true 12pi over 5 cause the formula is ark length =angle x radius

Answer 4

If sin Θ = 12 over 37, use the Pythagorean Identity to find cos Θ.

cos Θ = ± 35 over 37

cos Θ = ± 23 over 37

cos Θ = ± 35 over 12

cos Θ = ± 20 over 35

Answer 5

35/37

Answer 6

sin theta= opp/hyp
thus cos= adj/hyp
using pythagorean theorem we know x^2+12^2=37^2
solving for x we have=> x^2+144=1369
x^2=1225
x=sqrt(1225) =>37
answer: 35/37
