4. A restaurant is being built on the side of a mountain, the plans are shown below.
(a) The vertical curved wall of the restaurant is to be built of glass. What will be the surface area
of this wall?
(b) To be large enough to be profitable, the consulting engineer informs the developer that the
volume of the interior must exceed TR¹/2. For what R does the proposed structure satisfy this
requirement?
(c) During a typical summer day, the environs of the restaurant are subject to a tempertaure field
given by
T(x, y, z) = 3x² + (y− R)² + 16z².
A heat flux density V = -kVT (k is a constant depending on the grade of the insulation to
be used) through all sides of the restaurant (including the top and the contact with the hill)
produces a heat flux. What is the total heat flux? (Your answer will depend on R and k.)
