IBPS SO Prelims Exam Model Paper 9

Given:
Radius of park = 7 cm
Radius of cone = 3.5 cm
Raining 4 cm
Formula used:
Volume of a cylinder = π × r2 × h
Volume of cone = (

) × π × r2 × h
Calculation:
A circular park formed a cylinder due to filled with water 2 cm work as a height of a cylinder
Volume of a cylinder = volume of a cone
⇒ π × (7)2 × 4 = (

) × π × (3.5)2 × h
⇒ 49 × 4 = (
