Answer 1

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
