Question

1. find the area of a circle with the radius of 7 inches?

Explanation:

Step1: Recall circle area formula

The area of a circle is given by $A = \pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 7$ inches into the formula:
$A = \pi \times 7^2$

Step3: Calculate the squared radius

$7^2 = 49$, so $A = 49\pi$
If using $\pi \approx 3.14$, then $A \approx 49 \times 3.14 = 153.86$

Answer:

The area is $49\pi$ square inches (or approximately 153.86 square inches)
