look im no smarty but here
pi x diameter to get circumference, 7pi
x 8times = 56pi (the length)

radius=7/2Length of paper = circumference of the paper round the pencil Length of paper = 2πr=2*22/7*7/2=22mmNote: since the paper was wound eight times round the pencil Therefore, L =22mm *8= 176mmLength of paper = 180mm to 2 significant figures. Watsapp me for your tutorial 2347066081543
