Hello There!
[tex]GraceRosalia[/tex] 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=[tex]\pi[/tex][tex]r^{2}[/tex]
We know that r=4, so all we have to do is plug it into the formula:
A=[tex]\pi (4)^{2}[/tex]
Remember that only the radius is squared.
A=[tex]\pi *16[/tex]
A=50.265
Let's round to the nearest tenth:
A=50.3
Hope this helps you!
