volume of a right circular cylinder is v = (pi)(h)(r^2) if you want the answer in cubic meters the height and the radius must be in meters.
72.1 cubic metres, approx - assuming that the diameter is 18 feet and not some other units.
Volume = pi525 = 393 cubic meters rounded to the nearest integer
A right circular cone whose slant height is 9 inches and whose base has a diameter of 2 inches will have a volume of 36.757 cubic inches.
Volume = pi*1.52*5 = 35.34291735 cubic meters
A cylinder with a diameter of 7 meters and a height of 12 meters has a volume of 461.81 cubic meters.
The volume of a right circular cylinder with a diameter of 6.8 in and a height of 2 feet is: 871.6 cubic inches.
The volume is 141.37 cubic meters.
The volume is 47.12 cubic meters.
A cylinder with a radius of 3 meters and a height of 5 meters has a volume of 141.37 cubic meters.
The volume is 8.37758 cubic feet.
The volume is 461.81 cubic meters.
