Answer:
Step-by-step explanation:
The typical equation for the area of a circle is 
. Since the answer choices are in terms of <em>d</em>, the diameter of the circle, you will need to find <em>r</em> in terms of <em>d</em>.
To find <em>r</em> in terms of <em>d</em>, you know that the diameter of a circle is two times its radius. As an equation, this is
, or solving for <em>r</em>,
.
Now that you have an equation for <em>r</em> in terms of <em>d, </em>you can substitute <em>r</em> with 
from the original equation.
