A =

all real numbers except x = 36

all real numbers except x = 6

0 < x < 6

0 < x < 36

all real numbers

**Reiny**, Sunday, October 2, 2011 at 9:47pmI don't see any "figure below" , but I can surmise your figure shows a quarter circle in the first quadrant with a rectangle, whose base is along the x-axis, its height along the y-axis and it touches the quarter circle at (x,y)

Area = xy

= x√(36-x^2) or x(36-x^2)^(1/2)

for the domain, we have to make sure that the number under the √ does not become negative, so

0 < x < 6
