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?
Given:
The pillars of a temple are cylindrically shaped.
Each pillar has a circular base of radius $20\ cm$ and height $10\ m$.
To do:
We have to find the concrete mixture required to build 14 pillars.
Solution:
Radius of each pillar $(r) = 20\ cm$
$=\frac{1}{5} \mathrm{~m}$
Height $(h)=10 \mathrm{~m}$
Therefore,
The volume of one pillar $=\pi r^{2} h$
$=\frac{22}{7} \times \frac{1}{5} \times \frac{1}{5} \times 10$
$=\frac{44}{35} \mathrm{~m}^{3}$
Volume of concrete in one pillar $=\frac{44}{35} \mathrm{~m}^{3}$
This implies,
Volume of concrete of 14 pillars $=\frac{44}{35} \times 14 \mathrm{~m}^{3}$
$=\frac{88}{5}$
$=17.6 \mathrm{~m}^{3}$
