Solution :-
Inner Diameter of the well = 4.2 m
Radius = 4.2/2 = 2.1 m
Depth or Height of the well = 12 m
Curved Surface Area of cylinder = 2πrh
⇒ 2*22/7*2.1*12
⇒ 1108.8/7
⇒ 158.4 m²
So, Inner curved surface area of the well is 158.4 m²
Answer.
Inner Diameter of the well = 4.2 m
Radius = 4.2/2 = 2.1 m
Depth or Height of the well = 12 m
Curved Surface Area of cylinder = 2πrh
⇒ 2*22/7*2.1*12
⇒ 1108.8/7
⇒ 158.4 m²
So, Inner curved surface area of the well is 158.4 m²
