Answer:
Option A is correct
the approximate length of the minor arc is, 48 cm
Explanation:
Length of an arc is given by:
.....[1]
here r is the radius of the circle from the center and
is the angle in radian.
From the given figure, we have;
r = 23 cm
Use conversion:
1 degree = 0.0174533 radian
then
120 degree = 2.094396
radian.
Substitute these in [1] we have;
cm
Therefore, the approximate length of the minor arc is, 48 cm
