The table compares finn's distance from the starting point (in meters) and the time since he started (in seconds).

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units

Iam not sure , but probably 750 or 7.5

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.
