A skydiver is 1,200 meters above the ground when she opens her parachute. After opening the parachute, she descends at a constant speed of 7 meters per second. Write an equation to model the height of the skydiver above the ground, using h to represent her height above the ground and s to represent the number of seconds since she opened her parachute. Choose the correct number to fill in the blank h = s +

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
