how many cubic meters of Earth must be dug out to sink a well 16m in-depth, and 7 m in diameter...​

Answer 1

Answer:

Step-by-step explanation:

Step 1:

Given Data.

Sink a well = 16 m depth.

Diameter = 7 m

Step 2:

So we come to know  

Radius = Diameter / 2= 7 / 2 m

Height= 16m

Step 3:

Using the Formula

Volume of cylinder = π  4^2h

Volume of cylinder = 22 / 7 x 7 / 2 x 7 / 2 x 16

Volume of cylinder = 22 / 7 x 49 / 4 x 16

Volume of cylinder =616 m^2
