A well 2 m in radius and 14 m deep is to be dug. The cost of digging the well at Rs.1.20 per cubic meter is

A well is in the shape of cylinder

It is given that radius$\left(r\right)=2 \mathrm{m}$

Height/deep $\left(h\right)=14 \mathrm{m}$

Volume of cylinder $=\pi r^{2}h$

$=\frac{22}{7}\times 2\times 2\times 14$

$=176 {\mathrm{m}}^3$

Cost of digging the well $=176\times 1.20$

$=\mathrm{Rs}.211.20$
