Your question wants to know how much it turns in 1 turn. That means it wants to know the circumference.
The circumference formula is as follows:
![\sf{C= 2\pi r}](https://tex.z-dn.net/?f=%5Csf%7BC%3D%202%5Cpi%20r%7D)
The diameter is 50 cm, that means the r or radius is 25 cm.
So plugging that into the formula we get:
![\sf{C=2 \times 25 \times \pi}](https://tex.z-dn.net/?f=%5Csf%7BC%3D2%20%5Ctimes%2025%20%5Ctimes%20%5Cpi%7D)
Simplifying that, we get your final answer as
