A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm and the bicycle wheel makes 3 full rotations before stopping. How long is the trace of water left on the floor. Round to the nearest Cm

565.2cm

Step-by-step explanation:

Since we need to find out the circumference because the radius of the tire is 30cm. We take 30cm times 2. Which we get 60cm, then we take 60cm times 3.14 to get the circumference of 188.4cm. Then we take 188.4cm times 3 full rotations to get 565.2cm.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
