Perimeter of quadrant = 58 cm
=> pi *r / 2 + 2r = 58
=> 22r/14 + 2r = 58
=> (22r+28r) / 14 = 58
=> 50r/14 = 58
=> r = 58 * 14 / 50
=> r = 58 * 7 /25
=> r = 16.24 cm
=> pi *r / 2 + 2r = 58
=> 22r/14 + 2r = 58
=> (22r+28r) / 14 = 58
=> 50r/14 = 58
=> r = 58 * 14 / 50
=> r = 58 * 7 /25
=> r = 16.24 cm

Circumference of quadrant= 58cm (given)
1/4 × 2πr = 58
πr/2 = 58
πr = 116
Putting π = 22/7
22/7 × r = 116
r = (116 × 7) / 22
r = 812/22
r = 36.90 cm (approx.)
or r = 37 cm
1/4 × 2πr = 58
