Let the radius and height of the cylinder be r and h cm respectively. ∴ h = 1.30r Total surface area of the cylinder = 2833.6 = 2πr(h + r) ∴ 2833.6 = 2πr(1.3r + r) = 2πr(2.3r) = 4.6πr2 ∴ 2833.6 = (9.2/2) × (22/7) × r2 = 2833.6x 7 x 2/22 x 9.2 ∴ r2 = 196 ∴ r = 14 and h = 18.2 Amount of water displaced = Volume of the right circular cylinder = πr2h = (22/7) × (14)2× (18.2) = 11211.2 cm³
