Homework Help: Centroid of a Parabola

  1. Oct 12, 2011 #1
    The equation y = x2 describes a parabola. Find the x and y coordinates of the centroid of the area bounded by this curve, and the line y = 10m

    OK, show us what you have tried.

    I tried to intergrate from -3.16 to 3.16, b/c if you draw a perpinduclar line down from y=10 it intersects the x axis at those two values. I integrate the given equation y=x^2, but the number I got was 21, so i do not know if it is correct.

    I think this problem is asking you to determine the centroid of the area below y = 10 m and above y = x^2. Can you calculate the area of the enclosed parabola?
