Answer 3

On this one you are trying to find the length of the arc, so you need to use the circumference instead of the area.

Answer 4

Your angle is 240 degrees, and the formula for arc length is s=r(theta)
240 degrees, multiplied by (pi/180) gives it to you in radians, =4pi/3
then plug that into s=r(theta) and you'll get 12pi

Answer 5

oh so that would be 2pir

Answer 6

Right. And @scorcher219396 is also right. :)
