    8:45 super random that now we have this formula 4/(3pi) * r when it's on the center of the origin. Is this the only time we would use that formula? Other times I see in your videos you just use the center coordinates of the circle x, y

    For the third shape the rectangle can you explain how you got 12 for x and 4 for y instead of taking half of 2 which is 1 for x and half of 4 which is 2 for y . Please and thank you

    Thanks,but the answer is wrong it is 95.3, you made a mistake when you multipled area of the traingle twice, 2(X *A) but you {(2*X) *(2*A) }*it's wrong.

    Sir for the yi of triangle how did you come up with 16/3 instead of 8/3 sir enlighten me plss

  • @Christofboy1Vlogs
    @Christofboy1Vlogs2 жыл бұрын

    Keep in mind, the distance of the centroid depends on where your origin is. So the yi for the triangle is 4/3 (height is 4 taken to the 1/3) PLUS the distance from the origin to that triangle. 4” is the distance from the origin to the base of the triangle. Now all you do is add 4 + 4/3 to get your yi

    Hello sir, for the x centroid of the triangle why did you add the 12 to make it 14? I thought it was only b/3.

  • @Christofboy1Vlogs
    @Christofboy1Vlogs2 жыл бұрын

    Recall that our reference point is the origin. So the centroid of the triangle is the distance from (0,0) to the centroid of the triangle

    For right triangles, the centroid is 1/3 the distance from the right angle.

    You can choose how you want to set up your differential area. The set up would be different, but leads to the same result.

    Thanks so much.. But do you have any videos on where the composite figure lies in the negative x and y plane Does it affect your xbar and y bar values?

  • @Christofboy1Vlogs
    @Christofboy1Vlogs2 жыл бұрын

    Your coordinate system is key for determining the xbar and ybar values. If you, let’s say, change your coordinate system so that your x and y axis flip directions in this problem, you’d deal with sign changes for xbars and ybars (This also assumes you didn’t translate the origin of your system). The result should be the same if you work it out both ways.
