Bilal's fishing line was on a spool with a radius of 4cm. suddenly, a fish pulled on the line, and the spool spun 16 times before bilal began to reel in the fish. what is the distance the fish pulled the fishing line?

First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.

At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.

circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm

Now if it turns 16 times we'll have 16 times the circumference.

16 * (25.133 cm)

= 402.128 cm

the answer is 402 because on khan it asks to round to the nearest cm
