The pillars of a temple are cylindrical shaped.if each pillar has a circular base of radius 20cm & height 10cm, how much concrete mixture would be

required to build 14 such pillars? (\pi=3.14)



radius=20 height=100cm(1m=100cm)volume=pi*r^2*h

mixture of 14 pillars


0 0 0
Volume of cylinder=pi r²h
Volume of one cylindrical pillar=3.14 * 20*20*10
                                            =12560 cm³
concrete used to make one pillar=12560 cm³
concrete used to make 14 such pillar=12560*14
                                                     =175840 cm³
