Answer:
A cone
Step-by-step explanation:
we have
A(0, 0), B(0, 4) and C(2, 0)
Plot the figure
see the attached figure
The figure is a triangle
therefore
When this shape is rotated about the y-axis the 3-dimensional shape created will be a cone
where
The radius of the circular base of the cone is equal to r=AC
The height of the cone is equal to h=AB
The slant height of the cone is equal to l=BC
