Answer:
A≈920.75
Step-by-step explanation:
A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².
A=2πrh+2πr2=2·π·5.85·19.2+2·π·5.852≈920.75368

Formula of compound interest:
Compound continuously
A= Amount after t years
P= Principal
r= rate of interest
a)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=2 [ compounded semiannually]
(b)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=12 [ compounded monthly]
(C)
P=10,000, r=5.5%= 0.055 and t= 5 years
