Prism Mand pyramid N have the same base area and the same height. Cylinder P and prism Q have the same height and the same bas perimeter. Cone Z has the same base area as cylinder Y, but its height is three times the height of cylinder Y. The figures blank and blank have the same volume.​

Same length is comparing because it’s saying its the same and not different

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
