Question

16. 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 build 14 such pillars?​

Answer 1

Answer:

176000 cm³

Step-by-step explanation:

22/7*20*20*10*14

22*20*20*10*2

22*400*20

22*8000

176000cm³

Answer 2

Step-by-step explanation:

volume of 1 pillar = pie×r^2×H

= 22/7 ×400×10

= 88000/7 cm^3

vol of concrete = 14 × volume of 1 pillar

= 14 × 88000/7

= 176000 cm^3
