The length of the rectangle in #7 is 18 ft
I cannot see which region is shaded so I will solve for both:
1.
the radius of one circle is 3:
A=[tex] \pi [/tex][tex] r^{2} [/tex]
A=(3.14)(9)
A=(28.26)
The area of the three circles is 84.78 feet squared
Area of rectangle is 108 feet squared (16*8)
108-84.78=23.22
The area of the shape around the circles is 23.22 feet squared
2:
The area of 1 circle is 28.26
The area of 3 circles is 84.78 feet squared
The area of the circles in the rectangle is 84.78 feet squared.
