How is a toilet paper dispenser a wheel plus axle?

A toilet paper dispenser functions as a wheel and axle system because the roll of toilet paper serves as the wheel, while the central core through which it spins acts as the axle. When you pull on the paper, the roll rotates around the axle, allowing the paper to unwind smoothly. This design reduces friction and makes it easier to dispense the paper with minimal effort. Overall, the combination of the rotating roll and stationary axle exemplifies the simple machine concept of a wheel and axle.
