Answer:
30.4m
Step-by-step explanation:
Diameter(D) = 2r (radius)
D = 9.7m
r = 9.7m / 2
= 4.85m
C = 2πr
= 2π × 4.85m
= 30.47344873982099m
rounding - Leave it as is if the digit in the tenth is 4 or lower
- round it up if it's 5 or higher.

=> each teen carried the backpack for = (1/3) (3/5) of total Distance = 1/5
7√27 + 5√48
7 × 3√3 + 5√48
7 × 3√3 + 5 × 4√3
21√3 + 5 × 4√3
21√3 + 20√3
41√3 or 71.014
hope this helps, God bless!
