Answer:
1.05 s
Step-by-step explanation:
The generic form of a sinusoidal function is:
f(x) = A sin(2π/T x + B) + C
where A is the amplitude,
T is the period (time per revolution),
B is the horizontal offset (or phase shift),
and C is the vertical offset (or midline).
2π/T = 6
2π = 6T
T = π/3
T ≈ 1.05 s
