Answer:

h = 14

Step-by-step explanation:

Total surface area of cylinder =

 = 2\pi \times r \times (h + r)

According to the question,

880 = 2 \times  \frac{22}{7} \times 7 \times (h + 7)

6160 = 308 \times (h + 7)

 \frac{6160}{308} = h + 7

20 = h + 7

20 - 7 = h

h = 14

Hence height of cylinder = 14cm
