Answer: 158.53 cm
Step-by-step explanation:
We know that the ends of a fishing line spool are circular in shape.
Given : The area of an end of fishing line spool = (1)
Area of a circle = (2)
Circumference of a circle = (3)
, where r is radius of the circle.
From (1) and (2), we have
Circumference of fishing spool = (using (3))
i.e. Fishing spool required to wind around the spool one time
⇒ Fishing spool required to wind around the spool 10 times
Hence, you need 158.53 cm or about 159 cm of fishing line to wind around the spool 10 times.
