the perimeter of a quadrant of a circle of radius 7/2 cm is:
a)3.5 cm
b)5.5 cm
c)7.5 cm
d)12.5 cm

Perimeter of quadrant = Length of arc + 2 x radius
Perimeter of quadrant = (1/4 x 2 x 22/7 x 7/2) + 2 x 7/2
Perimeter of quadrant = 11/2 + 7
Perimeter of quadrant = 11 + 14 / 2 = 25/2 = 12.5 cm
Hope it helps!
