CIRCULAR WELL:-
diameter = d = 120cm
radius = r = 60cm [d÷2]
height (depth) = h = 950cm
Volume of the mud removed = Volume of cylinder
πr²h = 22/7 × 60 × 60 × 950
= 75240000 ÷ 7
= 10748571.42cm³
∴ The volume of the mud removed to make the well = 10748571.42cm³.

Find the radius:
Radius = Diameter ÷ 2
Radius = 120 ÷ 2 = 60 cm
Convert 60 cm into m= 0.6m
Volume = πr²h
Volume = π(0.6)²(9.5) = 3.42π = 10.75 m³
Answer: The volume of mud removed is 10.75 m³
