If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.
The answer depends on what the ratio is relative to!The ratio of a circumference to the area of a circle is half the radius.
Volume=(pi)(radius^2)(height)
Volume = about 56.55 units3
4/3*pi*(radius)^3
To find the volume we must first work out what the radius is: 2*pi*radius = 929 Divide both sides by 2*pi to find the value of the radius: radius = 147.8549421 volume = pi*147.85494212*6 volume = 412071.7235 cubic units
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
In a circle, the area of the circle is pi times the radius squared
1. Find volume of spheres = 4/3pr3 and multiply by 4 since there are 4 spheres.2. Find volume of units cell = l 3 = (2Ö2r)3.3. Find volume of empty space = vol unit cell minus volume of spheres.4. Divide volume empty space by volume of unit cell.It works out to 25.952

to obtain the ratio of surface area to volume, divide the surface area by the volume.
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
