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
