Question

The pillars of the temple are cylindrically shaped. Each pillar has a circular base of radius $20cm$ and height $10m$. How much concrete mixture would be required to build $14$ such pillars?

Answer 1

Given: Height$=10m$

radius $=20cm=0.2m$

We have to find it's volume to find the concrete mixture required.

The volume of the 1 cylindrical pillar $=\pi r^{2}h$

$=\frac{22}{7}\times 0.2\times 0.2\times 10$

$=\frac{8.8}{7}{m}^3$

Total mixture required to build 14 such pillars

$=\frac{8.8}{7}\times 14$

$=17.6m^3$

Hence, $17.6m^3$ concrete mixture is required.
