Answer:
Rs. 211.2/- is the Cost of Digging
Step-by-step explanation:
Given,
We know that A well is in the shape of cylinder and the volume for the cylinder is \piπ times square of radius and depth.
Radius (r) for well = 2m
Depth/Altitude of well, h = 14m
The volume of the wall = \pi r^2hπr

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

Answer:
here given that
r=3m
depth= height= 7m
well is cylindrical
therefore
volume of well= volume of cylinder
therefore
volume of cylinder = πr^2 h
= 22/7 ×3×3×7
= 198m^ 3
total amount of digging = 198×30
=₹ 5940
