A rope is wound 50 times round a cylinder of radius 25cm how long is the rope [use the value 3.14 for pi]
C = πd
d = 2r
In your case:
C = 50 * π * 2r
Insert values and calculate for C
7850
I don't really understand
A rope is wound 50 times round a cylinder of rzdius 25cm .What is the approximate length of the rope? Use the value of 3.14 for the
78.5m

To find the length of the rope wound around the cylinder, we need to find the circumference of the cylinder and then multiply it by the number of times it is wound around.
The circumference of the cylinder = 2Ï€r, where r = radius of the cylinder
Circumference of the cylinder = 2 × 3.14 × 25 cm = 157 cm
Total length of rope = 157 cm × 50 times = 7850 cm
Therefore, the approximate length of the rope is 7850 cm or 78.5 meters (rounded to one decimal place).
