Question

A piece of rope is wound around a cylindrical pipe 18 times, if the diameter of the pipe is 600 mm, how long is the rope???

Answer 1

Hey!

Circumference of the cylindrical pipe = 2 pie r
2*22/7*300mm
=1885.71

Length of rope=18*circumference
=18*1885.71
Answer=33942.78

Hope it helps u..!

Answer 2

The length of the rope is 33,912 mm, or approximately 33.9 meters.

Let's start by finding the circumference of the pipe, which we can then use to calculate the length of the rope. The diameter of the pipe is given as 600 mm, so the radius is half of that, or 300 mm.  The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is a constant equal to approximately 3.14.

So, the circumference of the pipe is:

C = 2πr = 2 × 3.14 × 300 mm = 1884 mm

Since the rope is wound around the pipe 18 times, the length of the rope is:

L = 18 × C = 18 × 1884 mm = 33,912 mm

Therefore, the length of the rope is 33,912 mm, or approximately 33.9 meters.
