Answer:
353.43 meters squared
Explanation:
Surface area = 2πr^2 +πdh
2·π·4.5^2 + π·(9) (8)
127.2345 + 226.1946
= 353.4291
Round to the nearest hundredth: 353.43 meters squared
Answer: 353.25
2πr^2+2πrh
2(3.14)(4.5)^2+2(3.14)(4.5)(8)
2(3.14)(20.25)+2(3.14)(36)
2(63.585)+2(113.04)
127.17+226.08
353.25
