Answer:

123.88 square units

Explanation:

r = radius of circle

= radius of sector

= Length of LM

= Length of MN

= 13 units

When the angle is measured in degrees:
Area of a sector:
(Angle OfSector)/(360^(o))×
\pi r^(2)

=
(84)/(360)×
[\pi (13)^(2)]

= 123.883
units^(2)

= 123.88 square units (Rounded to the nearest hundredth)
