I think you mean "radius". It's half of the diameter.

How do you find the ratio of a circle?
There is not one, sorry
How do you find ratio of a circumference?
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.
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
Find the ratio of the circumference of 4Cm?
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
How do you use pi to find a circle?
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
What is a ratio about?
There are two kinds of ratios. One is the ratio of a circle, which is half the circle's diameter, (which is the length of the circle across), which can be used to find the circles area. (the ratio squared multiplied by pi). The other ratio is something that looks like this 1:2 which work similar to fractions. Such as, for every one ____ there are two ___.
What is the ratio and diameter of a circle?
The diameter of a circle is the length of a straight line segment going through the circle and with endpoints on the circle itself. A ratio is a comparison of two numbers using the operation of division. That means that there is no such thing as the ratio of a circle. However, there is a ratio of the circumference of the circle (the length of the path around the circle) and its diameter. That ratio has the value pi, which is about 3.141592653589793...
What is the ratio of a circle with a radius of 8cm?
It depends on the ratio of what of the circle? Its circumference, diameter, area?
How do you find the area of a circle when the radius is unknown?
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.
How do you find the length of perimeter or circumference of a circle?
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
The ratio of the circumference and diameter any circle?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
