Answer: 28.27
Step-by-step explanation:
First, you can turn the diameter into a radius, giving you 3. Since the equation of an area in a circle is A=πr^2, you must square 3, giving you 9. Now you must multiply 9 with Pi, which is 3.14159265358, but just 3.14 for short. With that, you get about 28.27 as area.
Y=-x-13, they have the same slope but different y intercepts which mean they are parallel, and when graphed, the equation goes through (-9,-4). hope this helps :)
Answer:x-interpect: -9
y-intercept=6
slope=2/3

Answer: 17
Explanation: Distance is always positive. You add 12 to 5. If you walk 12 meters forward, and then 5 meters backward, you’ve still walked 17 meters.
Answer:
100 Miles
Step-by-step explanation:
Let it be for x miles.
40+15+0.25x=45+0.35x
10 =0.1x
x=100
The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80
