Curved surface area =2πrh=264 m2
∴ r=2642πh=132πhm
Volume =πr2h=π×132πh×132πh×h=924 m3
∴ h=132×132×722×924=6 m
Now, r=132πh=132×722×6=7m
answer
i.e., diameter of the pillar, d=7×2=14 m
∴ r=2642πh=132πhm
Volume =πr2h=π×132πh×132πh×h=924 m3
∴ h=132×132×722×924=6 m
Now, r=132πh=132×722×6=7m
answer
i.e., diameter of the pillar, d=7×2=14 m
