The area of the full circle is (pi) R2 = 64 pi.We call a full circle "360 degrees".The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is(5/6) x (64 pi) = 167.55 square units (rounded)
NO!!!!! pi is an irrational number, which means it cannot form a ratio/fraction. An approximation of 'pi' is the improper fraction '22/7'.
