Answer:
B
Step-by-step explanation:
x³ + y³ ← is a sum of cubes and factors in general as
x³ + y³ = (x + y)(x² - xy + y²)
with trinomial factor (x2 - xy + y2) → B
The circumference of the circle is equal to
C = 2πr, where r is the radius of the circle.
Substituting r = 1, the circumference is equal to
C = 2π
Since the arc ab is π/3, its fraction of the circumference is equal to
Fraction = π/3 ÷ 2π
Fraction = 1/6
