The figure created is a cone with a height of 2 units and a radius of 1 unit.
Which figure will be created?
Notice that we have a triangle, so if we rotate it around the y-axis, we will get a cone.
Because the rotation is around the y-axis, the height of the cone will be equal to the side AB of the triangle, so the height of the cone is 2 units.
And the radius of the cone is equal to BC, then we can see that the radius measures 1 unit.
Then the figure created is a cone with a height of 2 units and a radius of 1 unit.
