The perimeter of the entire figure is 62.8 cm.
Given, that the diameter of the inner semicircles is 9 cm and the width between the outer and inner semicircles is 2 cm.
The radius of the inner semicircle =4.5 cm and the radius of outer semicircle =5.5 cm (∵Diameter=9+2=11 cm)
We need to find the perimeter of the entire figure.
<h3>What is the perimeter?</h3>
A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
We know that, the circumference of a semicircle=πr and the circumference of two semicircles=2πr
Thus, the circumference of inner semicircles=2×3.14×4.5=28.26 cm
The circumference of outer semicircles=2×3.14×5.5=34.54 cm
The perimeter of the entire figure=28.26+34.54=62.8 cm
Therefore, the perimeter of the entire figure is 62.8 cm.

Answer: You can do this!
Step-by-step explanation: For D. The x= -1 and the y= 1 for E same thing the x= 7 and the y= 1 so look for the 7 on the x-axes and the one on the y-axes get it. I believe that you got this!

<u><em>Answer:</em></u>
79.8 (Guessing)
<u><em>Step-by-step explanation:</em></u>
for the side walls, split 19 in half, and get 9.5.
9.5 + 9.5 = 19
19 + 19 + 29.2 + 12.6
(2 walls) + (bottom floor) + (height/y)
79.8
Answer:
Substitute a value you want for x, for example:
if x = 1 then:
(1-7)/3 = -6/3 = -2
So,-2 would be the output for the imput x = 1
Answer:
has 25, wants 130, so he needs to save (130-25)= 105.
105/7= 15 weeks
25+7w= 130
