A stack of one dozen cookies of diameter 2.5 in. exactly fits in a cylindrical container of volume 14.726 in.3. Which is the thickness of each cookie???

Ineed on quadratic equations to solve problems

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.
