As the volume of cylinder is 448πcm³ and h= 7cm
Volume of cylinder = πr²h
So πr²h = 448π
Solving r² = 448/7 = 64 and r =√64 =8
Total surface area of cylinder = 2πr(r+h)
Putting the value
2π8(8+7) = 2π8(15)= 240π cm²
So the answer is 240πcm²
Volume of cylinder = πr²h
So πr²h = 448π
Solving r² = 448/7 = 64 and r =√64 =8
Total surface area of cylinder = 2πr(r+h)
Putting the value
2π8(8+7) = 2π8(15)= 240π cm²
So the answer is 240πcm²
