Last year, one model of a gasoline-powered car had a gas tank that holds 22 gallons of gas. This year, the carmaker is going to increase the capacity
of the gas tank by 15%. The car's mileage both last year and this year,
is 23 miles per gallon. Will this year's model be able to travel 100 miles
farther on a single tank of gas? Explain.

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
