When the point is on the x axis, then the y coordinate=0
when the pointis on the y axis then the x coordinate=0 as well
Answer:
1/6 is your answer ☺️☺️☺️
The length of an arc in a circle is radius x the angle (Ф).
Mind you angle Ф should be in radian.
1st let's convert 40° into radian
40/180 = x/π===> x=(π x 40)/180 ==> x = 2π/9 = 0.698 radian
so the arc length = 0.698 x 8 =5.585
