A concrete pillar has the shape of a cylinder. It has a radius of 3 meters and a height of 5 meters. If concrete costs $108 per cubic meter, how much did the concrete cost per pillar? Using 3.14 for pie

Given:- r - 3 Meter

h - 5 Meter

rate - 108$ Per M³

Sol:

Volume of Cylindrical Concrete Pillar= V = πr²h

V = 3.14×3×3×5 (π = 3.14)

Volume ≈ 141.37

Cost of Concrete pillar = 108$/m³

Cost = 108 × 141.37

Cost of Making Cylindrical Concrete pillar= $15,267.96
