To calculate the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle. Given that the radius is 7 inches, you can substitute this value into the formula:
\[
\text{Area} = \pi (7)^2 = \pi \times 49
\]
Thus, the area is:
\[
\text{Area} = 49\pi \text{ square inches}
\]
If you want a numerical approximation, you can use \( \pi \approx 3.14 \):
\[
\text{Area} \approx 49 \times 3.14 \approx 153.86 \text{ square inches}
\]
So the area of the circle is \( 49\pi \) square inches or approximately 153.86 square inches.
