Question

Diameter of wheel is 50cm. how far does it turn in metres in one turn

Answer 1

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}`

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 * 25 * \pi}`

Simplifying that, we get your final answer as


`\huge{\boxed{\bf{50 \pi = 157.08m}}}`
