The areas of a. circle is

the diameter is 2 times the radius, therefore
π (13/2)^2=132.665
Answer: about 132.7 in^2
Answer:
The third option, y=(-1/3)x-7
Step-by-step explanation:
To find a line perpendicular to an equation, you find the negative reciprocal of the slope. For instance, if you have an equation y=4x+5, the negative reciprocal is y=(-1/4)x+5. That is the equation to find a line perpendicular to this.
If you want to find a line parallel to the equation y=4x+5, all you have to do is come up with another equation that has the same slope. So, y=4x+8 would be a line parallel to the equation y=4x+5.
Answer:
1/3
Step-by-step explanation:
You can answer this as
9/27=1/3
and
3/9=1/3
and so 1/3 is the the constant proportionality for both figures
