Since well is cylindrical in shape,
⇒Volume of well =  \pi r²h
⇒Volume =( 22 * 1.5 * 1.5 * 21)/7
⇒Volume = 148.50 m³
Therefore,
The correct option is A. 148.50 m³  Ans.

Well is cylindrical because top and bottom surface are circle and the well is also circular in shape.
Height=21 m.
Radius of well=1.5 m
Therefore,
Volume=πr²h
=22/7*21*1.5*1.5 m³
=66*2.25 m³
=148.50 m³
Ans:The area is 148.50 m³(a)
