Answer:

113.14 square inches

Step-by-step explanation:

Area of circle is given by [tex]\pi r^{2}[/tex] where r is the radius. The radius is usually half the diameter hence for this case the radius will be 0.5*12=6 inches.

Taking [tex]\pi[/tex] as [tex]\frac {22}{7}[/tex] then the area will be[tex]\frac {22\times 6^{2}}{7}=113.14285714285714285714285714285714285714\ in^{2}\approx 113.14 in^{2}[/tex]

Therefore, rounded off to 2 decimal places the area is approximately 113.14 square inches
