What solid 3D object is produced by rotating the triangle about line m? Choose 1
A cylinder with height 4 units
A cylinder with diameter 8 units
A cone with height 4 units
A cone with diameter 8 units

A cone with diameter 8 units

Step-by-step explanation:

Hi, to answer this question we have to analyze the image given:

Since the figure is a triangle, if we rotate that figure about a line we will obtain a cone (so, it can't be a cylinder).

Now, the base of the triangle is 4 units. When we obtain the cone it will have a radius that will be equal to the triangle base. (4)

Since: Diameter = 2 radius

Diameter = 2 (4 units) = 8 units

A cone with diameter 8 units is the correct option.

Feel free to ask for more if needed or if you did not understand something.  

it's both, now can you answer my most recent question?
