Compete the statement about these similar cylinders. The circumference of the base of figure 2 is ___ π inches, and the area of the base of figure 2 is ___ π square inches. (Hint: The circumference of a circle = 2πr and the area of a circle = πr2, where r is the radius.)

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
