To find the area of the circle:

⇒ must know the area's formula ⇒
$\pi r^2$

Let's consider the information given

⇒ the radius' length is half of the diameter

⇒ thus the radius' length is 3.5 in

Let's calculate the area:

$Area=\pi r^2=\pi (3.5^2)=12.25\pi in^2$

The problem asks us to leave the answer in terms of '
$\pi$ ' which means that we won't multiply '
$\pi$ ' to the final answer, but leave it there,

Answer: 12.25
$\pi in^2$ or Choice (B)

Hope that helps!
