Expert Answer:

TSA equals 462 space cm squared
2 πr squared plus CSA equals 462

CSA space equals space 2 πrh equals 1 third cross times 462 equals 154
so comma
2 πr squared plus 154 equals 462
straight r equals 7
straight h equals 7 over 2
Volume space equals space πr squared straight h equals 539 space cm squared
