<h2>
Height of cylinder = 679.70 m</h2>
Explanation:
Compression strength = 1.7 x 10⁷ Pa
Normal force = Compression strength x Area
Radius = 46 cm = 0.46 m
Area of cylinder = π x 0.46² = 0.665 m²
Normal force = 1.7 x 10⁷ x 0.665 = 1.13 x 10⁷ N
So weight of cylinder = 1.13 x 10⁷ N
Density of concrete = 25 kN/m³ = 25000 N/m³
Volume of cylinder = Base area x Height = 0.665 x h
Weight of cylinder = 25000 x 0.665 x h
Equating
25000 x 0.665 x h = 1.13 x 10⁷
h = 679.70 m
Height of cylinder = 679.70 m
