x=10
option 2 is correct
Step-by-step explanation:
Area of circle = πr², π = 22/7 or 355/133. Here it is said to use '3.14'. I will use the same.
Volume = cross-section area * height
Cross-section area of bigger one = π(3m)²
Volume = π(3m)² * height
= 9π * 5 m³ = 45π m³
Cross-section area of smaller one= π(1m)²
Volume = π(1m)² * height
= π * 5 m³ = 5π m³
Since a large part(cylinder of 1 m is not here):
Required volume = total volume - volume of smaller circle(cylinder)
= 45π - 5π m³
= 40π m³ = 40(3.14) m³
= 125.6 m³
