TSA of sphere = 4 X pie X r X r

4 X pie X r X r = 5544

4 X pie X d/2 X d/2 = 5544

pie X d X d = 5544

d X d = 5544 ZX 7 / 22

d X d = 1764

d = root 1764

d = 42 cm

Ans: Diameter = 42 cm

4Πradius*radius5544 Πradius*radius=1386 Πsquare of radius = 1386 22/7 square of radius = 1386 square of radius = 441 radius = 21 cm so diameter = 2*21 diameter = 42 cm
