Answer 1

$\huge\boxed{♧ \: \mathfrak{ \underline{Answer࿐} ♧}}$

we know,

$\boxed{volume = \pi r {}^{2} h}$

so, volume of each pillar :

$\longmapsto 3.14 \times 1.7 \times 1.7 \times 12$

$\longmapsto108.89 \: m {}^{3}$

since, there are total 26 pillars,

total volume :

$\longmapsto108.89 \times 26$

$\longmapsto2831.14 \: \: m {}^{3}$
