Answer:
18
Step-by-step explanation:
x + (x + 1) + (x + 2) = 57
x + x + 1 + x + 2 = 57
x + x + x + 1 + 2 = 57
3x + 3 = 57
3x = 57 - 3
3x = 54
x = 54/3
x = 18
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.
