Option 4 : 972π cu.cm

**Given:**

r + h = 21 cm

T.S.A = 1188 sq.cm

**Formula used:**

T.S.A of cylinder = 2πr(h + r)

Volume of cylinder = πr^{2}h

**Calculation:**

r + h = 21

2πr(r + h) = 1188

⇒ 2 × 22/7 × r × 21 = 1188

⇒ r = 1188/(2 × 22 × 3) = 9 cm

so, h= 21 - 9 = 12 cm

∴ Volume = π × 9 × 9 × 12 = 972π cu.cm

**∴ The volume is 972π cu.cm**
