suppose that 8 turns of a wire are wrapped around a pipe with length of 60 inches and a circumference of 4 inches, so that the wire reaches from the bottom of the pipe to the top. what is the length of the wire
Answered by Steve
do you know how to calculate the length of a helix?

The radius is 2/π, so we have

x = 2/π cos θ
y = 2/π sin θ
z = 15/4π θ
0 <= θ <= 8*2π
