Perimeter of segment = 6.5 + 6.5 + 10.4 = 23.4 cm.
=> Length of arc = 10.4 cm.
Area of full circle of radius 6.5 cm = πr^2
= 22/7 x 6.5 x 6.5
Circumference of the full circle = 2πr
= 2 x 22/7 x 6.5
Area of sector
= 22/7 x 6.5 x 6.5 x 10.4/(2 x 22/7 x 6.5)
= 33.80 sqcm
Thanku for reading my answer..
