STEP 1:
We write out the formulas and the necessary values
[tex]\begin{gathered} \text{Area of circle =}\pi r^2 \\ \text{circumference of circle = 2}\pi r \\ \text{radius =}\frac{diameter}{2}=\frac{12}{2}=6\text{ inches} \end{gathered}[/tex]STEP 2
We substitute the values into the formula
[tex]\begin{gathered} \text{Area of the circle = 3.14 x 6 x 6} \\ Exactvalue=113.04\text{ square inches and Approx}imate\text{ value =113} \\ \text{circumference of the circle= 2 x 3.14 x6} \\ Exactvalue=37.68\text{ inches and approx}imate\text{ value = 38inches} \\ \end{gathered}[/tex]
