Question

The pillars of a temple are cylindrically shaped (see Fig. 13.26). If each pillar has a circular base of radius 20 cm and height 10 m, how much concrete mixture would be required to build 14 such pillars?

Answer 1

Correct Answer - `17.6 m^(3)`
Volume of concrete mixture in 14 pillars
`= ((22)/(7) xx (20)/(100) xx (20)/(100) xx 10 xx 14) m^(3) = 17.6 m^(3)`
