Calculate the cost of the window below using the table. Each pane is pricedseparately. The panes are square or circular.

Answer:$140(each square),$140(semi sphere),$140(each quarter ring)Total=$980Step-by-step explanation:Given4 squares of side 20 in1 semi circle of radius 10 in(half of side of square as seen in figure)2 quarter rings of thickness 10 and inner radius 10 and outer radius 20Each square are[tex]=side^{2} =20^{2} =400\\[/tex]Therefore each square costs=$140⇒Total cost for squares=[tex]=4\times 140=560[/tex]Area of semi circle[tex]=(pie)\times radius^{2}=(pie)\times 10^{2} =314.2..[/tex]⇒Cost for semi-circle= $140Area of each quarter ring[tex]=\frac{((pie)\times outer^{2})-((pie)\times inner^{2})}{2} =\frac{(pie)\times (20^{2}-10^{2})}{2} =\frac{(pie)\times 300}{2} =471.23..[/tex]⇒Cost of each quarter-circle= $140⇒Cost of both quarter-circle= $140+$140=$280Therefore total cost for window=$280+$140+$560=$980
