Answer:
3432 cm²
Step-by-step explanation:
Total surface area of cylinder = 2 × 22/7 × r × (r+h)
Given, radius (r) = 21 cm and height (h) = 5 cm.
=> TSA = 2 × 22/7 × 21 × (21+5)
=> TSA = 44 × 3 × 26 cm²
=> TSA = 3432 cm²

Answer:
3432
Step-by-step explanation:
total surface of cylinder=2πr (r+h)
=2×22/7×r×(r+b)
=R=21
=H=5
=2×22/7×21×(21+5)
=44×3×26cm²
=3432
