A circumference of 2 means a radius of 0.318. Thus, the volume of this cone is 0.477 units3

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 of a cone: V = (1/3)πr2hAnswer: Volume is ~ 9,911.46 ft3
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]
First find the radius which is 15.7/(2*3.14) = 2.5 Volume = 1/3*2.52*3.14*6 = 39.25 cubic ft
V = 2,617.99 ft3
The volume of this cone is 37,699 cm3
Volume of a cone = 1/3*pi*radius2*height
Volume of a cone = 1/3*pi*radius2*height
A cone with a base of 10cm and a height of 13cm has a volume of 340.34cm3
Cone volume = ( pi * radius2 * height ) / 3
