The volume of this cylinder is 1,570.8 units3
The volume of a cylinder that is 20 units high and 10 units in diameter is: 1,570.8 cubic units.
The volume of a cylinder 7 units high and 20 units in diameter is: 2,199 cubic units.
The volume is 176.71 units3
The volume of a cylinder 2.45 across by 1.50 high is: 7.072 cubic units.
Volume of a cylinder = πr²hV = 3.14159 x (1.5)² x 8V= 56.55
Volume of cylinder: pi*11.5^2*36 = 4761*pi cubic units
V = 311.02 units3
Volume = pi*52*20 = 1570.796 cubic units to 3 dp
pi times 0.1055 ie 0.33 units, to two significant figures
The volume of a cylinder that is 30mm in diameter and 700mm high is 494,800.84mm3
First you do the area for the base which is a=3.14r2. So 9 units is the diameter. 4.5 is the radius. The answer for the base is 63.6. So volume equals base x height. You do 63.6 x 2.5 and the answer is 159.
The volume of a right circular cylinder is the area of the base (which is pi times the radius squared) times the height of the cylinder. Working backwards, pi times radius squared times height is 6908 cubic units. The area of the base is pi times 10 squared, or pi times 100, or 314.16 square units for the area. That area, the 314.16 square units times the height is the 6908 cubic units, so to find the height, divide the area of the base into the volume. The 6908 cubic units divided by 314.16 square units is right at about 22 units, so the cylinder is about 22 units high.
