Answer 1

Answer:

$57\frac{3}{11}$ = c

or

$57.\overline{27}$ = c

Step-by-step explanation:

We know that the diameter of a circle multiplied by $\pi$ is the circumference, so we can create this equation:

180 = c * $\pi$

Your teacher told us to assume $\pi$ is 22/7, so we'll put that in

180 = c * $\frac{22}{7\\}$

To get c by itself, we divide both sides by 22/7

$\frac{180}{\frac{22}{7}}$ = c

Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22

180 * $\frac{7}{22}$ = c

Evaluate

$\frac{1260}{22}$ = c

$57\frac{3}{11}$ = c

If you want a decimal instead:

$57.\overline{27}$ = c
