Question

please help me!!!!!The coordinates A(0, 0), B(0, 3), C(4, 3) and D(4, 0) are graphed and connected together. What 3-dimensional shape will be created when this shape is rotated about the y-axis? Provide an explanation and proof for your answer to receive full credit.

Answer 1

would it be a pyramid????

Answer 2

or maybe a triangle???

Answer 3

What shape do you get when you plug in those four coordinate points?

Also remember when you're rotating around the y-axis, you're going to get a 3-Dimensional shape. A triangle is a 2D shape.

here's an additional resource that will help you :)
