Question 632458
A game Ginger invented is played on a semicircular field, as shown. The perimeter of the field needs to be enclosed with 8' netting . The netting costs $20 per linear meter.
 

 
What is the approximate cost of the netting used to enclose the playing field?


The straight portion of the semi circle is 60 meters
===================
If the "straight portion" is the diameter, then the circumference of the semicircle is pi*d/2 = 30pi meters.
The total = 60 + 30*pi meters
The cost = $30*(60 + 30*pi)
