How do you find the length of of the radius of a circle?
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
How do you find tha radius?
The radius is half the diameter. Draw a line that passes through the centre of the circle and measure it. This is the diameter. Halve it and you will have the radius.
How find you find the radius if you don't know the circumference?
With a ruler, or other suitable length measuring device. Measure the diameter (the widest part of the circle). The radius is half the diameter.
How can you use radius to find the diameter?
you double the radius to find the diameter.
How do you find the radius if you do not know the diameter?
You can measure it. Otherwise, you certainly have to know SOMETHING about the circle to calculate the radius, usually the diameter, the circumference, or the area. If you don't know anything at all about a circle, you can't find out the radius, either.

Do you have to find the radius for diameter?
Not necessarily. The diameter is only twice the radius, so that's an easy way to find the diameter. However, if you have the circumference, you can divide by pi to get the diameter, or just measure across the circle.

How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
How do you find the diameter?
The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter

How do you find diameter from radius?
diameter = 2*radius
How do you find the radius of a cone?
That depends what you are given. If you have an actual cone, you can measure the diameter of course.
How dou find diameter?

What is the diameter of a circle if the radius is 27 cm?
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
