Ответ:
to get the length of arc BC we shall proceed as follows;
angle DOC=48°
angle BOC=180-48=132°
curcumfrence of a circle is given by:
π×diameter×(theta)/360
The length of arc BC will be given by:
length,circumference=π×d×132/360
=11/30πd units
=1.152d units
where d is the diameter of the circle
