Question

the pillare of a temple are cylindrically shaped.if each pillar has a circular base of radius 20cm and height 10m how concrete mixture would be required to build 14such pillare?

Answer 1

The answer of this question is 28000

Answer 2

Answer:

14 pillars would require 17.6 m³ of concrete mixture.

Step-by-step explanation:

Radius of base of cylinder = 20 cm

Height of cylindrical pillar = 10 m = 1000 cm

Volume of each cylinder = πr²h

• $\frac{22}{7}\;*\;20\;*\;*\;20\;*\;1000\;cm^3$

• $\frac{8800000}{7}\;cm^3$

• $\frac{8.8}{7}\;cm^3$

(Since 1000000 cm³ = 1 m³)

Volume of 14 pillars = Volume of each cylinder × 14

(Since pillars are cylindrical in shape)

• $\frac{8.8}{7}\;*\;14\;cm^3$

• $17.6\;m^3$

∴ 14 pillars would require 17.6 m³ of concrete mixture.
