Question

How many cubic meters of soil must be dug out to
make a well 20m deep and 14m in
diameter ?​

Answer 1

Answer:

62.8cm

Step-by-step explanation:

we need to calculate the volume of well

since well is in the shape of a cylinder

formula of cylinder= πr^2h

diameter is 2

radius = diameter/2=2/2=1

height =20m

π = 3.14

volume of well=3.14*1*1*20

62.8 cubic meters
