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.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
