Question

The answer to number 7

Answer 1

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=$\pi$$r^{2}$
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.
