Find the radius of a circle that has an arclength of 17π/12 inches when a central angle measures 7π/9. Round to the nearest hundredth.

Answer 1

s = rθ
so, plug in your numbers
7/9 π r = 17/12 π
r = 17/12 * 9/7 = ____

Answer 2

[central angle (in radians)] * radius = arc length

r = (17 π / 12) / (7 π / 9) ... inches

Answer 3

@oobleck so would it be s=1.82?

Answer 4

I guess.
I assumed you could use your calculator.
lemme see.... yep 1.82
