Answer:
there are three different types of answers to this and all of them have to do with the perspective of pi
1) if you don't want to see the decimals and you want to leave pi alone your answer would be this
3pi
2) if you want to solve for pi it would be
9.43 respectively
3) if you want pi to just be narrowed down to 3 digits 3.14 your answer would be
9.42
Step-by-step explanation:
formula
C=2*pi*R
plug in
2*pi*1.5
Explanation:

Answer:
6/35
Step-by-step explanation:
change 2/5 to 14/35 so the denominators are even.
after that you get -8/35+14/35
then you get 6/35
The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.
