If you are talking about TSA.
Let h be height
Then Area= 2πr(h+r)
= 2×22/7×7(50+7)
= 44×57
= 2508cm²

radius of cylinder , r = 7cm
height of cylinder , h = 50cm
curve surface area of cylinder = 2πrh
= 2 × 22/7 × 7 × 50
= 44 × 50
= 2200 cm²
total surface area = 2πr² + curve surface area
= 2 × 22/7 × 7² + 2200
= 44 × 7 + 2200
= 308 + 2200
= 2508 cm²
