That's easy
alrighty
we can see that each of those curves from K to N and from N to L are just 1/4 of the circumference of the circle
the circles have centers at J and M
so
we have 2 of those 1/4 circumfernce so a total of 2/4 or 1/2 circumference
circumference=2 times pi times radius
radius=JK=JN=NM=ML=7
we want half so
perimiter=1/2 times 2 times pi times 7
we are given pi=22/7 so
perimiter=1/2 times 2 times 22/7 times 7
perimiter=2/2 times 22
permiter=22cm
the perimiter is 22
wait, I forgot abou the bottom part (KL)
that's just twice the radius or 2*7=14
22+14=36
the perimiter is 36cm
The amount of interest she will earn in one year will be 5 dollars and 12 cents.
<h3>What is Simple interest?</h3>
The normal interest levied on the amount borrowed from any bank on a yearly basis is called the simple interest.
Given that:-
- The interest of 3.2% per year
- Invests $160 and no money will be added or removed from the investment.
The simple interest amount will be:-
SI = ( P x R x T ) / 100
SI = ( 160 x x 3.2 x 1 ) / 100
SI = $5.12
Therefore the amount of interest she will earn in one year will be 5 dollars and 12 cents.

So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct
