∙ 15y agoThe volume of a cone is equal to 1/3 pi*r2*h. C=2*pi*r, so r=C/(2*pi) and
V=1/3*[C/(2*pi)]2*h

∙ 15y agoYou 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
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
Improved Answer:-Volume of a cone in cubic units = 1/3*pi*radius squared*height
If you mean the volume of a cylinder then divide the circumference by 2*pi to find its radius and so:- Volume in cubic units of the cylinder = 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 of a cone = (1/3)*(area of base)*(height). Area of a circle = pi*radius². But you know circumference. Circumference = 2*pi*radius. Rearrange: radius = C/2/pi. Substitute this in for radius above: Area = pi*(C/2/pi)² = C²/(4*pi). Volume = C²*h/(12*pi) [C is circumference, h is height]
Volume of a cone = 1/3*pi*radius2*height
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
Volume formula for a cone: 1/3*pi*radius squared*height
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

V = 1/3 x pi x r^2 x h r = C/2*pi
The volume of this cone is 15,400 cm3
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
