To find the area of a pizza (which is a circle), you can use the formula for the area of a circle:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle. The radius is half of the diameter. Since the diameter of the pizza is 12 inches, the radius is:
\[
r = \frac{12}{2} = 6 \text{ inches}
\]
Now, plug the radius into the area formula:
\[
\text{Area} = \pi (6)^2 = \pi \times 36
\]
Using the approximate value of \( \pi \) (3.14):
\[
\text{Area} \approx 3.14 \times 36 \approx 113.04 \text{ square inches}
\]
So, the area of the pizza is approximately 113.04 square inches.
