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.
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
There is no direct ratio. The area is related to the square of the radius by the factor "pi." A = (pi) r2 (Pi is about 3.1416)
It depends on the ratio of what of the circle? Its circumference, diameter, area?
The ratio of surface area to volume increases. The area of a sphere is proportional to its radius squared. Volume is proportional to radius cubed. As the radius increases, the volume increases more than the surface area. As the radius decreases, the volume decreases more than the surface area, so the ratio of surface area to volume increases.
The ratio of a circle's circumference to its area is called the reciprocal of half the radius. The ratio of the circumference to its radius is called two times pi.

a. 2 to 5.
How to find the area of a fillet. Is it area =0.2146 radius squared
If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.
Radius = +sqrt(Area/pi)
