Answer:
Step-by-step explanation:
Area of the segment = (Angle / 360) * pi * radius^2
= (30 / 360) * (22/7) * 7 * 7
= (1/12) * 22 * 7 = 154 / 12 = 77/6 = 12.83 cm^2

Answer:
12.83 square cm
Step-by-step explanation:
Area of a segment of a circle is
= π R*R*x/360
where x is the angle of the segment in degrees
= (22*7*7*30)/(7*360)
= 22*7/12
= 77/6
= 12.83 cm^2
