Answer:

113.14 square inches

Explanation:

Area of circle is given by
\pi r^(2) 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
\pi as
\frac {22}{7} then the area will be
\frac {22* 6^(2)}{7}=113.14285714285714285714285714285714285714\ in^(2)\approx 113.14 in^(2)

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