it will be in cylindrical shape
given height = 21m
radius = 1.5m = 15/10m = 3/2m
volume of cylinder = volume of earth dug up
volume of cylinder = πr²h
= 22/7×3/2×3/2×21
= 22/7×9/4×21
= 11×9/2×3
= 297/2
= 148.5 m³
given height = 21m
radius = 1.5m = 15/10m = 3/2m
volume of cylinder = volume of earth dug up

height = 21m
radius = 1.5m =3/2m
volume of cylinder = πr²h
=[tex] \frac{22}{7} * \frac{9}{4} *21 \\ \\ [/tex]
