Find the area of a circle with diameter 18 in. Use the value 3.14 for it, and do not round your answer.
Be sure to include the correct unit in your answer.

The mode of the numbers is 29.

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.
