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.  

answer: the equation matches the regression

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
