A cylinder

A cylinder 108 cm high has a circumference of 24 cm. A string makes exactly six complete turns around the cylinder while its two ends touch the top and bottom. (forming a spiral around the cylinder).
How long is the string in cm?

Correct answer:

x =  180 cm

Step-by-step explanation:

h=108 cm c=24 cm  c = 2π r r=c/(2π)=24/(2 3.1416)3.8197 cm  x=h2+(6 c)2=1082+(6 24)2=180 cm

Finding the length of the string is the same as finding the length of the hypotenuse of a triangle with a height of 48 cm and a base of a number of turns*circumference
