Answer 2

Hello There!

$GraceRosalia$ is here to help you!

We are given that

d=8 in.

We know that the radius is 1/2 of d or r=d/2. So the radius is 4.

However, we have to find the area.

The formula for the area of a circle is:

A=$\pi$$r^{2}$

We know that r=4, so all we have to do is plug it into the formula:

A=$\pi (4)^{2}$

Remember that only the radius is squared.

A=$\pi *16$

A=50.265

Let's round to the nearest tenth:

A=50.3

Hope this helps you!
