Question

A figure is located at (0,0), (-3, -4), and (-3, 0) on a coordinate plane. What kind of 3-D shape would be created if the figure was rotated around the x-axis? Pls provide an explanation and proof.:)

Answer 1

Answer

Cone

Step-by-step explanation

The figure made by these 3 points is a right-angled triangle as shown in the next graph:

where one of its sides lays on the x-axis.

When a right-angled triangle is rotated around one of its two short sides (in this case, the one on the x-axis), a cone is made.
