Answer:
Step-by-step explanation:
volume is 448∧ height = 7cm
volume = ∧r²h
⇒ 448∧ = ∧r²h
⇒448∧ = ∧r²*7
⇒448/7 = r²
⇒r =√64=8 cm
now curved surface area = 2∧rh
= 2*22/7*8*7
= 352 cm²

Vol 448πcm2
H is 7cm
Vol= πrrh
=> 448 = rr(7)
R= 8cm ( not -8)
CSA= 2πrh
= 112π
TSA= 2πr(r+h)
= 16(56)π solve the rest
