PLS HELP ASAP 27 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

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

Step-by-step explanation:

A and C are obviously wrong because the height is 2 units up, so A and C aren’t the answer. Which leaves two: B and D. It wouldn’t generate a cone, so the answer is D.

answer:

1. 0.04
