Gene's frying pan is 14.5 inches in diameter. what is the circumference of his frying pan

C=2(3.14)(r)
C=2(pi)(7.25)
C=45.55
that's assuming we use pi and not 3.14 instead.

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.

The third one i'm pretty sure
