True or false B. If the height increases, then the radius must also increase, and if the height decreases, then the
radius must also decrease in order for the volume to stay the same.

The surface area would be 576 because you multiply all the numbers then multiply that number by 6

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.
