Chapter 14, Problem 47(choose chapter or problem)
Building Design A new auditorium is built with a foundation in the shape of one-fourth of a circle of radius 50 feet. So, it forms a region R bounded by the graph of
\(x^2 +y^2 =50^2\)
with \(x\ \geq\ 0\) and \(y\ \geq\ 0\). The following equations are models for the floor and ceiling.
Floor: \(z=\frac{x+y}{5}\)
Ceiling: \(z = 20 + \frac{xy}{100}\)
(a) Calculate the volume of the room, which is needed to determine the heating and cooling requirements.
(b) Find the surface area of the ceiling.
