Question

1.The wheel of a unicycle has a radius of 14 in. About how many rotations does it take for the wheel to travel 440 in.?

Answer 1

What we can do first is since we have the radius, we use the circumference formula which is \(\sf C=2\pi r\)

And then whatever we get from that, to figure out how many rotations it did, we do \(\sf\large\frac{440}{C}\)
