PLS HELP ASAP 40 POINTS what 3d object is generated by rotating the rectangle about the x-axis.

a. a cylinder. with a radius of 2 and height 4

b. a cone with a radius of 4 and height 2

c. a cone with radius2 and height 4

d. a cylinder. with a radius of 4 and height 2

Answer C is correct if i wrong don't judge i have feelings to.

Step-by-step explanation:

D-A cylinder with a radius of 4 and height of 2

Step-by-step explanation:

A and C are obviously wrong because the hight is 2 units up, 4 is the base, so A and C are not one of the options. Which leaves two: B and D. It wouldn’t generate a cone, so the answer is D.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
