Question
A cylindrical tank with a radius of 7 m is half-filled
with water. If a cuboidal block of dimensions 2 m × 5.5 m × 7 m is submerged completely into the tank, find the rise in the water level of the tank.Solution
Volume of the block = 2 × 5.5 × 7 = 77 m³ Rise in water level = Volume of block / Cross-sectional area of cylinder Cross-sectional area of cylinder = πr² = π × 7² = 154 m² Rise in water level = 77 / 154 = 0.5 m Correct option: a
