Question
The formula for the circumference of a circle is $C=2 \pi r$ . Find the circumference of a circle with adiameter of 12 in. (diameter $=2 r ) .$ Use the symbol $\pi$ in your final answer.
Step 1
However, we are given the diameter of the circle, not the radius. We know that the diameter is twice the radius, or $d=2r$. Show more…
