Ans:
Solution:-
Diameter = 7 m so, radius = 3.5 m
H = 20 m
Volume of the earth dug out = π r² h
= 22/7 × 3.5 × 3.5 × 20
= 770 m³
Area of the platform = Length × breadth
⇒ 22 × 14 = 308 m²
Height of the platform = Volume of the earth dug out/area of the platform
⇒ 770/308
Height of the platform = 2.5 m Answer
