A creeper plant is climbing up and around a cylindrical tree trunk in a helical manner. The tree trunk has a height of 420 inches and a circumference of 32 inches.
If the creeper covers a vertical distance of 60 inches in one complete twist around the tree trunk, what is the total length of the creeper?
A. 476
B. 458
C. 490
D. 410
E. 450

Read Solution (Total 1)

width of the rectangle is 32 inches
height of the rectangle is 60 inches
apply pythagoras theorem l=(60^2+32^2)^1/2=68 inches
no total revolutions=420/60=7
so total length=68x7=476
