1/3 * 22/7(Pie) *r square * height = Volume
So
r = Whole Under Root (Volume/height*7/22*3)
:D Hope it helps
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
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 formula for a cone: 1/3*pi*radius squared*height
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 = 1/3*pi*radius2*height To find the radius make it the subject of the above formula.
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
Where V=volume, r=radius, and h=height: V = (1/3)*Pi*r2*h
The volume of a cone whose base has a radius of 8cm and whose height is 10 cm is: 670cm3
The radius of a cone with the height of 4.5 inches and a volume of 3.375 pi cubic inches is: 1.5 inches.
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.
Improved Answer:-Volume of a cone in cubic units = 1/3*pi*radius squared*height
The radius IS given, since height of hemisphere = radius of hemisphere!
