Answer: 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.
