You have a fishing line spool with an end that has an area of 20.0 cm2. how much fishing line do you need to wind around the spool 10 times?

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.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
