diamter=2xradius, so if you have the diameter, divide by 2 and you have the radius. r=d/2

What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
Is the diameter of the circle always greater than the radius of the circle?
No, only if the diameter is bigger than the radius is the radius smaller than the diameter.
What is the formula for 6x5x4x3x2x1?
THAT IS THE FORMULA! Just solve that! Formulas are only needed to calculate certain measurements or numerals in algebraic equations used to determine things like a radius, or diameter of a circle.
How do you find the area of a circle that has no diameter?
The circle must have a diameter, so maybe your teacher just didn't tell you the diameter. In order to figure out the question, you need to know some information about the circle. Weather it's the radius, circumference, or diameter. So here's how you find area if you only have each of the three: 1. If you just have the radius, then square the radius. This means multiply radius times radius. Or say the radius is 4. Squaring it is 4 times 4. So once you find out the answer for radius squared, multiply radius squared by pi. (Probably use 3.14 for pi) Then there's your area. 2. If you only have the circumference of a circle, then you need to find the radius. In order to do that, you need to find the diameter. To find the diameter of a circle, you take the circumference and divide it by pi. (3.14) then you have your diameter. Since the radius is half the diameter, divide the diameter by 2. Then, once you find the radius, you may look at step 1 and use those steps to find out the area. Since your question is wondering how to find the area without knowing the diameter, then you can multiply the radius by 2 to find out the diameter. Even though you don't need to know the diameter to find the area. You just do (r times r) times pi (3.14)
What is the diameter and circumference of the circle whose radius is 10 meter?
The diameter is 20. (The diameter is twice the radius. The radius is from the center to any edge of the circle.)The circumference is 62.83. ( The diameter X Pi (3.14... equals the circumference.)OR:Using only the radius: (2 X Pi X radius will also equal the circumference.)In this example 2 X 3.14 X 10 (2 X 3.14 = 6.28 X 10= 62.8)
Formula to find radius of a sphere?
Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
How do you determine the radius if you only have the diameter?
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
What is the formula for finding the circumference of a circle when you only know the radius?
Circumference = 2 x pi x radius
How do you find the radius of a circle only knowing the circumference?
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
How do you find the radius of a cylinder if you only have the diameter?
The radius is half the diameter.
What is the radius of a circle with the diameter of 56 centimeters?
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
Is the diameter of the circle always greater than the radius of the circle?
No, only if the diameter is bigger than the radius is the radius smaller than the diameter.
How many diameter and radius are in a circle?
Well,there is only one from each.The radius is the half of the diameter,e.g if the diameter is 4 the radius is 2
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
How do you find the radius of a cone knowing only the diameter?
The radius is half the diameter, so just divide the diameter by 2.
How do you find the diameter if you only have the radius?
Multipy by 2 for the diameter
