Answer: 4.067units.
Step-by-step explanation:
(a) The highlighted arc is the major arc. That is , it covers from G to I.
(b) The length of the major arc will be
πr0°/180 where the angle substended at the center by the highlighted arc is
360° - 127° ( the angles if the arc not highlighted)
= 233°
Though this radius of the circle was not given so we are going to find the arc length without necessarily defining the radius.
Arc length = π × r × 233°
---------------
180
= 3.142 × r × 233°
------------------
180
= 4.067runits.
