Hi friend, here is the required answer:-
Radius=7 cm
Total Surface Area=968 cm²
2πr(r+h)=968 cm²
2×22/7(7+h)=968
44+44/7h=968
44/7h=968-44
44/7h=924
1/7h=924÷44
1/7h=21
h=21×7=147 cm
Hope this helps you...

dimensions of the cylinder are
r= 7cm
let height = h cm
given TSA = 968cm²
2πr(r+h)=968
⇒2*22/7*7 (7+h) =968
⇒44(7+h)=968
7+h = 968/44
7+h =22
h=22-7
h=15 cm
r= 7cm
let height = h cm
given TSA = 968cm²
2πr(r+h)=968
⇒2*22/7*7 (7+h) =968
⇒44(7+h)=968
7+h = 968/44
7+h =22
h=22-7
h=15 cm
