Search results for "A circular well of 21m depth is dug up so that the radius of the well is 1.5m. What is the volume of the earth dug up



We know that volume of a sphere = πr²h
According to the question, r = 1.5m; h = 21m
Thus volume of Earth dug = 22/7 x 1.5 x 1.5 x 21
= 22 x 1.5 x 1.5 x 3
= 148.5 m³

Hope that helps !!
