These dimensions are not possible for a cylinder.
A cylinder with a diameter of 7 meters and a height of 12 meters has a volume of 461.81 cubic meters.
A cylinder that has a diameter of 10 meters and a height of 3 meters has a surface area of 251.33m2
A cylinder with a height of 10 meters and diameter of 4 meters has a surface area of 150.8m2
A cylinder with a height of 20 meters and a diameter of 10 meters has a surface area of 785.4m2
The volume of this cylinder is: 9.425 m3
2.5019 METER
Your diameter is double the radius. So the diameter is 6
The volume is 461.81 cubic meters.
The curved surface area is 502.65m2
Volume = pi525 = 393 cubic meters rounded to the nearest integer
If cylinder diameter = 2.55 metres and height = 3.5 metres then volume = 17.87 cubic metres. If cylinder diameter = 3.5 metres and height = 2.55 metres then volume = 24.53 cubic metres.
It is: pi*72*10 = 2155 cubic meters rounded to nearest integer
