Question

A figure is located at (2, 0), (2, -2) and (6, 0) on a coordinate plane. What kind of 3-D shape would be created if the figure was rotated around the x-axis?

Answer 1

Figure A located at (2,0) , (2,-2) and (6,0)

Then shape about this coordintes is:

If the triangle shape rotate about x - axis then its create the shape of cone and height of cone is (6-2=4) and tha radius of cone is (0-(-2)=2).
