When granular materials fall, they form conical piles. The angle of slope, measured from the horizontal, at which the material comes to rest is called the angle of repose. The angle of repose is related to the height h and base radius r of the conical pile by the equation 0= cot h -1! When certain granular materials are stored in a pile 14 feet high, the diameter of the base of the pile is 25 feet. h (a) Find the angle of repose for these granular materials. 0 = D° (Round to two decimal places as needed.)
