If you draw it out, you'll find that you're basically finding the area under the function from x = 0 to x = 9. So it's just a simple definite integral.
Hey
I don't understand how to find the area enclosed by functions. I tried my text book, but it is pretty confusing. Can someone show me the steps to this problem, please?
*R is closed by y= square root of x , x=9, and y=0
a) Integrate with respect to the x -axis
b) Integrate with respect to the y-axis.
Thanks!
