A circular path runs around a circular plot. If the circumference of the plot and the path are 44m and 88m, respectively, find the width of the path

7 meters

Step-by-step explanation:

circumference of path=88m

⇒2πr=88

⇒2.  

7

22

.r=88

⇒r=14m

circumference of plot=44m

⇒2πr  

′

=44

⇒2.  

7

22

.r  

′

=44

⇒r  

′

=7m

therefore width of path=r−r  

′

=14−7

=7m

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
