volume of cylinder =πr^2h
448π=πr^2h
r^2=448/7=64
r=8cm
now by putting formula for curved surface area and total surface area. u will get answer.

volume of cylinder =πr²h=448πcm³=r²h=448=r²(7)=448
r²=64
r=8cm
csa of cylinder=2πrh
= 2(22/7)(8)(7)
352cm²
tsa of cylinder=2πr(r+h)
2(22/7)(8)(8+7)
754.28
hence proof
