So my question is find the circumference of the circle in terms of Pi then use the approximation 3.14 for pi and approximate the circumference.
How would I do this? The radius of the circle is 2m.

  1. C = Pi * d

    C = 3.14 * 4

    3 * 4 = 12

    I'd estimate the circumference at close to 13 m.

  2. Ok so the circumference would be 6.28m, and the approximation would be 12.56 or 13 like you said.
