The length of segments ab is 24
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
Answer:
39.2
Step-by-step explanation:
We need to find the solution of 7 copies of sum of 8 fifths and 4.
Now, 8 fifths = 
Sum of 8 fifths and 4 = = 
Now, 7 copies of
means that we meed to multiply
7 times
7 copies = 
7 copies = 39.2
Hence, the solution is 39.2.
<em>The ratio of shared costs of mean=2:3.
One person paid the cost </em>£<em>52.20, so let the other person paid the cost be X.
</em><em>(2/3)=(52.20/X)
</em><em>X=(52.20</em>×3)/2
X=26.10×3
X=78.30
So the gross cost paid by both the person = £(78.30+52.20)
⇒£130.60
