The volume is 12,383,000 mm3
Height = 1000/(pi*42) = 19.89436769 mm
(Height times Pi) times (radius squared) If the height is measured in millimeters, then the radius must be measured in millimeters. Pi is 3.14 more or less.
Volume = 1/3*pi*42*9 = 150.7964474 cubic millimeters
The volume of a sphere that has a radius of 10 millimeters is: 4,189 mm3
if its a cone: volume= (1/3) base* height or volume= (1/3) pi *radius*radius[r squared]* height
Vol = (1/3) * pi * radius2 * height = (1/3) * 3.14159265 * 32 * 9 = 84.823 mm3
the answer is do it yourself and youll actually get a good answer instead of some mumbo jumbo like 24.5!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If the height is 9 and the volume is 21, then the radius = 0.8618
(assuming its a cylinder) volume = pi * radius2 * height so: radius = square root ( volume / ( pi * height ) )
The volume of a cylinder is (pi)r^2h. This means the volume is dependent on both the height and the radius of the cylinder. So, one must know Volume and either radius or height to calculate height or radius respectively.
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
