Question

the pillars of a temple are cylindrical shaped. If each pillar has a circular base of radius 20cm and height 7 m

Answer 1

Answer:

Considering it to a solid cylinder, for amount of concrete making are cylinder = volume of cylinder

∴ Amount of concrete mixture required to fild 14 such pillars =14× volume of a cylinder−−−−−(1)

If Volume of cylinder where =πr

2

h

x=radius

h=height

Volume =π×x

2

×h

=π×20×20×10 cm

3

=4000π cm

3

=4000×3.142 cm

3

=12568 cm

3

Substituting it in equation (1)

=14×12568

=150816 cm

3

∴ Amount of concrete mixture required to build 14 such pillars =150816 cm
