The Gillis family has a swimming pool with the shape as shown. They want to make a pool cover to protect it during the harsh winter. How many dollars, to the nearest cent, will they need to spend on material for the cover if the fabric costs $5.00 per square meter?

Solution

Total perimeter =

=top length+curved length + bottom length + slant length

= 6+ 2*3.14*2+9+sqrt(4^2+3^2)

=32.56

Total cost = 32.56*5 = $162.8
