Answer 2

Answer:

Area of sector = X/360×πr×r

Area of sector = X/360×πr×rHere X (Theta)= 72°

Area of sector = X/360×πr×rHere X (Theta)= 72°Therefore,

Area of sector = X/360×πr×rHere X (Theta)= 72°Therefore, area = 1/5 ×22/7×7×7

Area of sector = X/360×πr×rHere X (Theta)= 72°Therefore, area = 1/5 ×22/7×7×7area = 30.8 cm square.

Area of sector = X/360×πr×rHere X (Theta)= 72°Therefore, area = 1/5 ×22/7×7×7area = 30.8 cm square.HENCE , area is 30.8 cm square.
