Jayne stopped to get gas before going on a road trip. the tank already had 4 gallons of gas in it. which equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x?
a) y=4+x
b) y = x − 4
c) y = 4 · x
d) y = x ÷ 4

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
