Circles are material that is applicable in real life. We often encounter circular surface shapes, such as wheels, wall clocks, coins, and pipe surfaces. This research designs a learning trajectory regarding calculating arc lengths and tangents to circles formed by rubber used in packaging several identical and non-identical pipes through the application of learning using the Indonesian Realistic Mathematics Education (RME) approach. The method used goes through 3 phases, namely: (1) Experimental preparation; (2) Experiments in class; and (3) Retrospective Analysis. This design consists of five stages: (1) calculating the length of the rubber binding between the two pipes; (2) calculating the length of the three pipe rubber ties; (3) calculating the length of the four pipe rubber ties; (4) draw conclusions; and (5) Excercise. The results show that a formula has been found to calculate the length of rubber binding several identical pipes.
