**Explanation: **When the plate rotates in the oven, it covers angular displacement θ. However, we want to find the linear distance in the given time of 2.0 min. Now, for one complete revolution of the plate, θ = 2π. Since, the plate takes 6 revolutions in one minute, therefore, angular displacement of the plate in one minute = 6 × 2π = 12π.
