A right cylinder with ,
- Radius of base = 6 inches
- Volume = 396
Volume of the cylinder can be calculated as :
here
- r denotes radius
- h denotes height
- π = 3.14
Plugging the values in the above formula

In feet,
1 metre = 3.2808 feet
3.5 metre = 3.2808 ft × 3.5
= 11.48 feet (approximately)
Hence, The the height, in feet, of the cylinder is 11.48 feet
