Expert Answer:

Volume of the building = Volume of the cylinder + volume of Hemisphere                                           = r2h + 2/3 r3....................(1) since, diameter is equal to the height      2r = h...................(2) By substituting in the equation 1. Volume = 17.7 = r2(2r) + 2/3 r3                   17.7 = 8/3 r3.......................................(3) Find the value of r from equation -3 and then find h using equation 2.
