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.
