Sagot :

TSO
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:

[tex]\sf{C= 2\pi r}[/tex]

The diameter is 50 cm, that means the r or radius is 25 cm.

So plugging that into the formula we get:

[tex]\sf{C=2 \times 25 \times \pi}[/tex]

Simplifying that, we get your final answer as

[tex]\huge{\boxed{\bf{50 \pi = 157.08m}}}[/tex]
