Diameter of each pillar = 2m

radius = diameter ÷ 2 = 2 ÷ 2 = 1m

height = 2cm = 0.02m

radius = diameter ÷ 2 = 2 ÷ 2 = 1m

height = 2cm = 0.02m

Diameter of each pillar =2m = 200 cm

Radius, r of each pillar = 100 cm

Height, h = 2 cm

Hence, Volume occupied by each pillar = πr^2h = 3.14*(100)^2*2 = 62800 cm^3
