A circle with radius 4 has a sector with central angle of 8/5pi radians.

(64/5)π units²

Step-by-step explanation:

The area of this sector would be:

Given central angle

*(area of whole circle)

            2π rad

In this case, the area of the sector is:

      (8/5) π rad

* π(4 units)^2

            2π rad

and this reduces to:

(4/5) * π*16 units²      or  (64/5)π units²

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
