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.

Step-by-step explanation:
-3+x=11
+3 +3
x=14
Answer:150
Step-by-step explanation:
So every year the interest will be $1000 * 5 / 100 = $50. That is, after 3 years 3 * $50 = $ 150. Simple interest does not take into account the reduction of the principal but calculates the interest over the same initial amount, in this case $1000. So, the answer is $150, which is the result of $50 times 3.
Answer:
130.5
Step-by-step explanation:
<em>145% of 90 = 145% * 90</em>
<em>145% = 1.45</em>
Substitute: 1.45 * 90
Multiply: 130.5
You find the HCF which is 8
you divide 32 and 24 by 8
which will give you 4 and 3 respectively
therefore there will be 4 slices of turkey and 3 slices of cheese in each sandwich.
and there will be 8 sandwiches...
