Leigh bought a conical candle wax mold. The height of the mold is 16.8 inches and the radius of the inside of the top of the conical mold is 2.2 inches. She fills the mold completely with candle wax so that it is level with the top of the conical mold.

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.
