For this case the area of the sector is given by:
 A = (S '/ S) * (pi) * (r ^ 2)
 Where,
 S '/ S = relation of arcs
 r: radius of the circle
 Substituting values we have:
 A = (7.4/360) * (3.14) * (13 ^ 2)
 A = 10.9080111
 Rounding off we have:
 A = 10.9 cm^2
 Answer:
 the area of sector is:
 A = 10.9 cm^2
