Answer:
12π, option C is correct.
- Using a shorter form of pi, the first step is to assign the default value for every circumference-radius problem. The r is the same value as radius, so in this case, that would be 6 m.
[tex]C = 2\pi r[/tex]
- Next, split this value into an equation, breaking down all 3 parts.
[tex]2\pi r = 2 * \pi * 6[/tex]
- Using the short form of pi, if you multiply all 3 numbers, your answer rounds to 37.68 m(Which is not on-the-nose, just an estimate that is extremely close to the real number).
