Total surface area of cylinder = 2πr(h+r)
→1936cm²= 2*22/7*7(h+7)
→1936= 44(h+7)
→h+7= 1936/44
→h+7= 44
→h= 44-7
→h= 37
Thank You!!!

Answer:
Step-by-step explanation:
Let the height of the cylinder be h cm.
Radius of the base (r) = 7 cm
Total surface area of cylinder = 2r (h + r)
1936 = 22 2 × × 7 ( 7)
7
h
1936 = 44 (h + 7)
h + 7 = 44
h = 44 – 7
h = 37
