if the diameter of the base of cylinder pillar is 4 meter and it's height is 21 meter then the cost of construction of pillar at rs 1.50 per cubic meter is
Answers
Answer:
Rs 395.8 is required for construction of the piller.
Step-by-step explanation:
Diameter of the base of the cylindrical piller is = 4m.
Height of the piller =21 m.
Volume of the piller = π×(4/2)×(4/2)×21 = 263.89sq m.
Cost of construction = Rs 1.5 /sq m.
Therefore total cost of construction = 263.89 ×1.5 = Rs 395.8
cost of construction of pillar = 396 Rs if Diameter base of cylinder pillar is 4 m and it's height is 21 m
Step-by-step explanation:
Piller is Filled With Material
Hence to find cost of construction of pillar
we need to find Volume of Piller
piller is in cylindrical form
Volume of Cylinder = π R²H
R = Diameter/2 = 4 /2 = 2 m
H = height = 21 m
π = (22/7)
Volume of Piller = (22/7) * 2² * 21
= 88 * 3
= 264 m³
cost of construction of pillar at rs 1.50 per cubic meter = 264 * 1.5
= 396 Rs
cost of construction of pillar = 396 Rs
