I cannot imagine you could. both the radius and the height are considered in it's volume formula. this stands to reason as two cones of different radii can have the same volume, by the larger radius one having a smaller height and vice versa
if you the accidentally this sentence
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
volume of a cone = 1/3 x pi x radius2 x height Rearrange the formula: height = volume of cone divided by 1/3 x pi x radius2
volume=pi*radius squared*height/3, where radius is the radius of the cylinder (and will be the radius of the base of the cone),and height is the lenth of the cylinder.
Volume of a cone = 1/3*pi*radius2*height To find the radius make it the subject of the above formula.
You must have another parameter
You will also need the height of the cone. From circumference you can calculate the radius (circumf/Pi = radius). Volume of cone = 1/3 height x Pi x radius2
Volume formula for a cone: 1/3*pi*radius squared*height
Improved Answer:-Volume of a cone in cubic units = 1/3*pi*radius squared*height
Radius of cone = 19/2 = 9.5 mm Volume = (1/3) PI r^2 h, where r is the radius and h is the height, We need to know the height of the cone to find its volume.
Volume = Base x Height /3 Where base is the area of the base circle (pi*radius*radius) and Height is the perpendicular distance from the base to the apex of the cone
Without another piece of information, the radius alone isn't enough to tell you the volume of the cone. You really need the height too.
