A wheel with a radius of 25 cm made 12 revolutions. Find the distance the wheel has traveled.

Let’s use the formula for the circumference:

L = 2πr, where n = 3.14, r = radius of the circle.

Let’s calculate the circumference of the wheel:

2 * 3.14 * 25 = 157 cm.

Let’s calculate how far the wheel has traveled, for this we multiply the circumference of the wheel by the number of revolutions that it made:

157 * 12 = 1884 cm.

Answer: the wheel has traveled 1884 cm.
