Answer:
h=37
Step-by-step explanation:
Total surface area of a cylinder=2πr(r+h)
=> 1936=2×22/7×7(r+h)
7and 7cancels out
1936=44(7+h)
1936/44=7+h
44-7=h
h=37
hope it helps:)

Step-by-step explanation:
Let height be 'h'
radius = 7 cm
Total surface area = 1936 CM sq
Total surface area =2π r (7 + h)
1936 = 2 * 22/7 * 7 (7 + h)
1936 * 1/2 * 7/22 * 1/7 = 7 + h
44 = 7+h
44 - 7 = h
h=7
height is 37 cm
