The formula for finding the area of a circle is A=pi(r^2). In this problem, you do 3.14 x 23^2.
3.14 x 23^2--->3.14 x 529--->1661.06 yards.
If you still don't understand and still need help, be free to ask me! Hope this helps!
I don't think a number like that exists :/
You can subtract the populations to see by how many more people/citizens does country B have
To find the slope, graph the points they give on the question. Then make a right triangle connecting the points. To find the slope divide the rise/run. The rise is how many down from the top point to the second and the run is how many across. Divide those 2 numbers you find. To tell if it is negative or positive, look at the line. If it goes from left to right, it is negative. But if it goes right to left than it is positive. I hope this helps! If you have any more questions let me know! I am going over this in class now and have gotten the hang of it.
