Question
A right circular cylinder having total surface area of
18480 cm2 is immersed in a vessel completely filled with water. If the height of the cylinder is 40% more than its radius, what is the amount of water displaced (in cm3)?Solution
Let the radius and height of the cylinder be r and h cm respectively. ∴ h = 1.40r Total surface area of the cylinder = 18480 = 2πr(h + r) ∴ 18480 = 2πr(1.4r + r) = 2πr(2.4r) = 4.8πr2 ∴ 18480 = (9.6/2) × (22/7) × r2 = 18480 x 7 x 2/22 x 9.6 ∴ r2 = 1225 ∴ r = 35 and h = 49 Amount of water displaced = Volume of the right circular cylinder = πr2h = (22/7) × (35)2 × (49) = 188650 cm³
