Answer:
Circumference = 2 π R where R is the radius
= 2× π × 35
= 70 π
Length of rope= 5 × circumference ( 70π)
5× 70π
= 5× 70 × 3.14
= 1099mm
( π = 3.14)

Answer:
1099mm
Step-by-step explanation:
since the rope is being wound around a cylinder, which is circular in shape, we first find the circumferance using the equation 2πr.
so in this case we say 2×π×35mm⇒ 219.8
the rope is wound 5 times. 219.8×5⇒ 1099mm
