Judge the wheel rolling cycle, the distance traveled is equal to the wheel diameter times the circumference ()

Judge the wheel rolling cycle, the distance traveled is equal to the wheel diameter times the circumference ()

That's right

Why is the circumference of a circle = diameter times π (PI)

Because π is a fixed value of circumference / diameter of a circle
Just like t for time and V for speed
I'll learn an e later
