Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to

we have


substitute


step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians

Answer:
55
Step-by-step explanation:
add 25 and 30 to get 55
a triangle always equals 180 so
180-55=125
y is a straight line with x which equals 180 so
180-125=55
Trick question: none, as i can do 600 or 606, etc
2y/(y²-8y+5) - 1/(y-5)=
2y/(y-5)(y-3) - 1/(y-5)=
Least common multiple=(y-5)(y-3)
2y-1(y-3) / (y-5)(y-3)=
2y-y+3 / (y-5)(y-3)=
y+3 / (y-5)/y-3)
Answer : (y+3) / (y-5)(y-3).
you did right, congratulations!!.
