Thread: Trig word problems

I'm new to trig and I missed the first three lessons because i was absent. I've done almost all of my homework but this one problem I just can't grasp

A spiral staircase has 13 steps. Each step is a sector with a radius of 36 inches and a central angle of pi/7.

Through what angle would you rotate by climbing the stairs? Include a fourteenth turn for stepping on the landing.

okay, so I've gotten this far -

14 steps
radius = 36
angle in radians = pi/7 (right?)
angle in degrees = 25.7

Basically all stated in the problem. HALP PLZ.

one complete rotation

radius doesn't matter

okay I got that now. and that didn't help me at all. suicide brb.
What after that? I'M SO BRAINDEAD

is it 50pi?

what are you talking about? ... I gave you the solution in my last post.
