Verandah of a school is supported by 10 pillars. Each pillar is 4 metre high and its diameter is 63 cm. how much concrete mixture is required to construct the pillars?
​

Answer 1

Step-by-step explanation:

height = 4 m.

Radius = r = 63/2 cm

=> (63/200) m.

Volume of concrete in 1 cylindrical pillar,

=> πr^2h

=> (22/7) × (63/200)^2 × 4

=> 1.2474

Volume of concrete in 14 cylindrical pillars,

=> 14 × 1.2474

=> 17.46 m^3

Volume of concrete mixture = 17.46m^3.

Hope it helps.
