Question:

The cross-sectional area of a beam cut from a log with radius 1 foot is given by the function

where x represents the length, in feet, of half the base of the beam. See the figure.

(a) Find the domain of A.

(b) Use a graphing utility to graph the function A = A(x).

(c) Create a TABLE with Tb1 Start = 0 and Î”Tb1 = 0.1 for 0 ‰¤ x ‰¤ 1. Which value of x maximizes the cross- sectional area? What should be the length of the base of the beam to maximize the cross-sectional area?
