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

Answer:
Yes, she will have $1.96 left
Step-by-step explanation:
Initial cost : $60
Discount : 25%=0.25
Calculating discount : 60 * 0.25 = 15
Calculating cost after discount : 60-15 = 45
Sales tax : 6.75%=0.0675
Calculating sales tax : 45 * 0.0675 = 3.0375≈$3.04
Calculating final cost : 45+ 3.04 = $48.04
Can she buy the printer : 50 - 48.04= $1.96
Answer : yes
