Step-by-step explanation:
the arc length of a while circle of 360° is the circumference of the circle, which is
2×pi×r
now, our radius r is 15 in.
and we are not dealing with the whole circle of 360° but only with a fraction of that : 30° out of the 360°
so, the arc length is
2×pi×15×30/360 = 2×pi×15×1/12 = pi×15/6 = pi×5/2 =
= 7.853981634... in
Answer:
x=10.5
