In the diagram are three pulleys, A, B and C, connected with belts. A’s radius is 1 cm, B’s larger radius is 3 cm and smaller radius is ½ cm, and C’s radius is 2 cm. Also, B’s larger and smaller wheels have the same axis and move together.

⒜ When pulley A rotates once, determine the distance that the belt connected to A moves.

⒝ When pulley A rotates once, determine how much pulley B has rotated.

⒞* When pulley A rotates once, determine how much pulley C has rotated.
