The pillars of a temple are cylindrically shaped. If each pillar has a circular base of radius 20 cm and height 10 m. How much concrete mixture would be required to built 14 such pillars?
Given,
Radius of base of cylindrical pillar = 20 cm = .20 m
Height = 10 m
So, concrete require to make a pillar = πr2h = 
= 
Concrete required for 14 such pillars = 
2
