144=PS2+7PS which has only one solution which make sense, namely 9

Then QS=sqrt(144-81)

Step-by-step explanation:

Anika [276]

Answer:

1413.86 ft^2.

Step-by-step explanation:

The diameter of the circle = 50 - 2(18)

= 50-36

=  14 ft.

So its radius is 7 ft.

The total area of the blue shape

= 2(35 * 18) + 3.14*7^2

= 1413.86 ft^2.
