    How do I rotate this about the x-axis?

    The directions are: Rotate the region around the x-axis and find the volume The actual problem is: Region bounded by y = 4 - x^2, y = 0, x = -2, x = 0 The answer I keep getting for the volume is 321.6990877, but the answer in the back of the book is (256π) / 15. The steps I took to get my...

    Rotate About the line y = 4

    Find the volume of the solid generated by revolving the region bounded by the graphs of the equation about the line y = 4. I set y = y to find the boundaries. I found the boundaries to x = o and x = 3. V = pi INT from x = 0 to x = 3 of the function (x)^2 dx. My Answer: 9pi...

    Rotate About x-axis

    Find volume of solid generated by revolving the region bounded by the graphs of the equations about the indicated lines. y = x^2, y = 4x-2x^2 ABOUT X-AXIS. I set x^2 = 4x-2x^2 to find my limits of integration. I found my limits to be [0,2]. See picture for more information.

    Through what angle does the arrow rotate when it moves 1 inch on the gauge?

    The arrow on a car’s gasoline gauge is ½ inch long. Through what angle does the arrow rotate when it moves 1 inch on the gauge? Give your answer in degrees (round to the nearest whole degree). I got 115 degrees as an answer and i wanted to see if i got it right.

    Trying to figure out how to rotate an ellipse...

    Hi, So, I have been trying to figure out how to rotate an ellipse in the form of: x^2/a^2 + y^2/b^2 = 1 My guess is that making a translate vector of T<x^2, y^2> will do the trick. My goal is simply to make the ellipse not vertical or horizontal. My reasoning is because ^2 will have moved the...

    Move and Rotate a point around a new origin

    I'm trying to do something like this: The pyramid is linked to the box. I have the positions and rotations of both the green box and the green pyramid. The axis intersecting the green box is at (0, 0, 0) with a rotation of (0, 0, 0). I want to move and rotate this group to the new axis...

    volumes rotate about y = x

    i don't know how to start this problem. Instead of rotating about a horizontal and vertical line, it requires you to rotate about the line y =x determine the volume bounded by the curve when y = x^4 and y =x between x = 0 and x = 1 are rotated about the line y =x Thanks

    volumes rotate about y axis

    The region of the curve y = \frac{e^x}{x} bounded by x = 1 and x = 2 and y = 0, is rotated about the y axis. Find the volume of the solid. i drew the diagram and it doesn't look doable. Would I have to consider volumes by slicing? thanks

    When I try to rotate a graph using the shell method, I get a non-solvable quadratic!

    When I try to find the points of intersection I get 0 = (a quadratic equation that has no intercepts!) My work is attached as #13 on page 12 of the pdf. The question is: "Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given...
