Mary is painting the rooms of her new house before she moves in. It takes her about 4 hours to paint one room. Her friend Kevin is going is going to help and it takes him about 3.5 hours to paint one room. Her house has 8 rooms so how long will it take them to finish painting?

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
