Federico works in a small workshop where he makes wheels for the calenders. A customer has asked you to put an iron liner around a wheel to prevent wear. Federico does not know how much material he will use to cover the wheel, so it occurred to him to place it on the floor, make a mark on the part that touched the ground and turn it until it coincides with the floor again. Finally, he measured the track left by the wheel, as shown in the drawing. Is Federico's procedure to obtain the wheel circumference appropriate? why?

the mark left by the wheel is 2.99 m long. estimate the measure of its diameter; You can base yourself on the picture above.

the diameter of the wheel measures about 0.95 m. what is the ratio between this element and the circumference?

( here it is in English if it helps since the photo is in spanish, it’s all the same btw)
