Please help me! Will fan and medal! i have the answer already. The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together. What three-dimensional shape will be created when this shape is rotated about the y-axis? Provide an explanation for your answer to receive full credit.

    it's probably because since all the of the points are in the first quadrant, it only regarded that area... when those points are connected I have a box, but when I drew it on here, it was not to scale.

    I know in Euclidean Geometry assuming we have isometry (blah spelling) [ retains it shape] if we rotate it 90 degrees or 180 degrees, we still have a box.

    I'm wondering how that box became a cylinder after rotation because cylinder is a round shape.

    the door panel is a rectangle revolving that rectangle around the central axis carves out a cylinder

    what about for a box? would that cylinder also apply as well?
