Answer:5) c= 25.12 cm
6) c= 282.6 m
7) c= 13.188 mi
8) c= 6.28 cm
Step-by-step explanation:
C= 2 x pi x r
Circumference = 2 x 3.14 x radius ( radius is half the diameter of the circle)
Answer:
No solution (if the fractions were squared)
Step-by-step explanation:
If you multiply by 5..you would get k^2=-1/243. Since you can't have a negative squared, you would have no solution
Simplified the answer is 1/4 or 0.25 in decimal form
Answer:
Her centripetal acceleration during the turn at each end of the track is 
Step-by-step explanation:
Total distance covered in one round , D= 400 m
Time taken to cover one round , T = 1 min 40 s = 100 sec
Speed of runner , 
Now centripetal acceleration is given by

where 


Thus her centripetal acceleration during the turn at each end of the track is
