Four cylindrical concrete pillars support the roof of a building. each pillar is 4m long and 50cm in diameter, (a) calculate the total volume of the four pillars in meter cube,(b) if 1m cube of concrete has a mass of 2.1 tons calculate the total mass of the four pillars in tons

4

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
