Answer:
8π(2.5)^2
Step-by-step explanation:
volume = π * r^2 * h
v = π * (2.5)^2 * 8
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>

Bus A would do the route 13 times
Bus B would do the route 12 times
So since it is a 50 mile radius around one point, then it makes a circle. You need to find the are of the circle to find out how much land that is. you use the equation A=

r². Plug 50 in for r and you get A=

50². 50²=2500. Then you multiply that by 3.14 (rounded number of pi) and you get 7850. So, now you have the total land area, now you need the percent of the total Alaskan land. To do that, you make a proportion.

=

Then, you cross multiply and get 785,000=586,412x. To find out what x is, you divide both sides by 586,412 and get x=1.3386 % . Hope this helps!!
