Sign in nowLet the radius and height of the cylinder be r and h cm respectively. ∴ h = 1.20r Total surface area of the cylinder = 16940 = 2πr(h + r) ∴ 16940 = 2πr(1.2r + r) = 2πr(2.2r) = 4.4πr2 ∴ 16940 = (8.8/2) × (22/7) × r2 = 16940 x 7 x 2/22 x 8.8 ∴ r2 = 1225 ∴ r = 35 and h = 42 Amount of water displaced = Volume of the right circular cylinder = πr2h = (22/7) × (35)2 × (42) = 161700 cm³
