. If you walk around a circular path TWICE, and the circle has a diameter of 100 m, how far did you walk in TOTAL?

The total distance traveled was 638.3m.

How to calculate the distance traveled?

To calculate the perimeter of a circle we perform the following operations:

We must keep in mind that the radius of a circle is equal to half the diameter, so the radius of this circle is 100m divided by 2.

  • 100m ÷ 2 = 50m

So the radius of this circle is 50m.

Subsequently, to find the perimeter of the circle we apply the following formula:

  • 2 × π × radius of the circle = perimeter of the circle.

  • 2 × 3.14 × 50 = 314.15m

According to this operation, the distance traveled in one lap would be 314.15m. So in two turns it would be:

314.15m × 2 = 638.3m
