Answer:
21 G = 390miles
G = 390/21
G = 18.57
gallons of gas should he expect to use to travel 635 miles to Daytona Beach
= 635/18.57
=34.19
<em><u>Hence,</u></em><em><u> </u></em><em><u>3</u></em><em><u>4</u></em><em><u> </u></em><em><u>gallons </u></em><em><u>is </u></em><em><u>the </u></em><em><u>correct</u></em><em><u> answer</u></em>

Answer:
c = 25
Step-by-step explanation:
A (-6, 5), B (-2, 4), <em>C (-2, 5) </em>
Form a triangle by adding a new point to the graph.
*in this case it is coordinate C
- First step: Find the distance between points A and C
From A to C there are 4 units.
- Second step: Find the distance between points B and C
From B to C there are 9 units
Next you need to use the pythagorean theorem to find the length of A to B
Now use the lengths you have to find the missing length.
So we know that surface area is top circle +bottom circle+ (circumfurence times height so) 2(π(radius)^2)+(height(2π(r))) so fill in the blanks
it's kind of hard to see but πr means pi times radius (r)
2πr^2+((4.2)(2)(π)(r))=628.3
factor out the 2 so the equation would mean
2((πr^2)+(4.2πr))=628.3
divide both sides by 2
πr^2+4.2πr=314.15
what's interesting is that the first few digits of pi are 3.1415 so we aproximate pi as 3.14 and divide both sides by 3.1415
r^2+4.2r=100
subtract 100 from both sides
r^2+4.2r-100=0
factor
(x-8.11812)(x+12.3181)=0
so (if xy=0 then x or/and y must be 0 so)we set them to 0 so
x-8.11812=0
x=8.11812
second one
x+12.3181=0
x=-12.3181
since radii (or any legnth) cannot be negative, we can cross this solution out so
radius=8.11812
