Answer:

False; True; True

Step-by-step explanation:

If the radius is 4, the area of the circle is

pi*r*r = pi * 4 * 4 = 16pi; The second statement is true.

The entire circle's "angle" is 2pi, so the sector takes (2pi/3) / 2pi of it all, equal to 1/3 of the entire circle - hence the area of the sector is

16pi * 1/3 = 16pi/3; the first statement is false

The length of the entire circle is 2 * pi * r = 2 * pi * 4 = 8pi

The sector is 1/3 of that, so 8pi/3; the third statement is true.
