Question Prompt: question_prompt: What is the area of a circle if its circumference is $18.84$ units?
Step $1$ : Step $1$ : Use the circumference to find the radius. $\newline$ Circumference formula: $C = 2 \cdot \pi \cdot r$ $\newline$ $18.84 = 2 \cdot \pi \cdot r$ $\newline$ $r = \frac{18.84}{2 \cdot \pi}$
Step $2$ : Step $2$ : Calculate the radius. $\newline$ $r = \frac{18.84}{2 \times 3.14}$ $\newline$ $r = \frac{18.84}{6.28}$ $\newline$ $r = 3$
