Answer:
The answer to your question is 9923 cm²
Step-by-step explanation:
Data
radius = 30.8 cm
height = 20.5 cm
Surface area = ?
Process
1.- Write the formula to calculate the surface area of a cylinder
SA = 2πr² + 2πrh
2.- Substitution
π = 3.14
SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)
3.- Simplification
SA = 5957.459 + 3965.192
4.- Result
SA = 9922.65 cm² or SA = 9923 cm²
