Answer 1

Answer:

$35.33\ m^3$

Step-by-step explanation:

Given that,

Height of the cylindrical well, h = 20 m

The diameter of the well, d = 1.5 m

Radius, r = 0.75 m

We need to find the volume of the well. This will be the amount that is dug out to make a well. So,

$V=\pi r^2 h\\\\V=3.14\times (0.75)^2\times 20\\\\V=35.33\ m^3$

So, $35.33\ m^3$ soil was dug out to make a well.
