Answer:

volume = 539 cm³

Step-by-step explanation:

T.S.A of a cylinder = 2πr (h+r) = 462 cm²

C.S.A of cylinder =  2πrh = 462 / 3 = 154 cm²

Volume = ?

2πrh = 154

πrh = 77

now, 2πr (h+r) = 462

2πrh + 2πr ² = 462

154 + 2πr ²  = 462

2πr ²  = 462 -154 = 308

πr ² = 154

r ² = 49

r = 7

Volume of cylinder =

πr²h = 77 * 7 = 539 cm³
