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.
