The amount of earth that must be dug is 22 m³.
• Given data :
Depth / height of the well = 7 metres
Diameter of the well = 2 metres
• So, the radius of the well
= Diameter of the well / 2
= 2/2
= 1 metre
• Now,we have to calculate the volume of the well by using the following mathematical formula :
= π × (radius of the well)² × height of the well
= π × (1)²× 7
= 22/7 × 7
= 22 m³
So,we need to dig 22m³ of earth to construct the well. (Answer)
