Find the area of the sector whose are is making an angle of 90° at the center of a circle of radius 3.2 Cm.	Choose the correct choice:
A) 56.72 Sq.Cm
B) 56.22 Sq.Cm
C) 56.82 Sq.Cm
D) 56.42 Sq.Cm
E) 56.32 Sq.Cm
Area of the sector = 90/360 × πr(power)2   = 90/360 × 22/7 × 3.2 × 3.2   = (11 × 10.24)/2 = 112.64/2=
