2πr(r+h)=968
2*22/7*7(7+h)=968
44/7*7(7+h)=968
7+h=968*7/44*7
h=22-7
h=15 cm
2*22/7*7(7+h)=968
44/7*7(7+h)=968
7+h=968*7/44*7
h=22-7
h=15 cm

Radius of the cylinder=7 cm
Total surface area (TSA)=968 cm
ATQ:-
2πr(h+r)=968
2×22/7×7(h+7)=968
44(h+7)=968
44h+308=968
44h=968-308
44h=660
h=660/44
h=15
So,the height of the cylinder is 15 cm.
