Answer:
sqrt7/4
Step-by-step explanation:
sin is opposite/hypotenuse which means sqrt63/12 then sqrt63=3sqrt 7 and simplifies get (sqrt7)/4 Done!
Answer:
its b, and why does everyone want brainllest
Step-by-step explanation:
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
