It varies on how large the diameter and radius is.
True, but with the radius you know to double it and you have the diameter.
If you muliply Pi (3.14....) times the diameter, you get the circumference.
So radius = circumference divided by Pi, with that answer (which is "diameter")then divided by two.

If the diameter of a circle is 14mm what is the radius?
The radius would be 7 millimeters.
The circle has a radius of 22 millimeters what is the diameter of a circle in centimeters?
Well, isn't that just a happy little question! To find the diameter of the circle, you simply need to multiply the radius by 2. Since the radius is 22 millimeters, the diameter would be 44 millimeters. And if you want to convert that to centimeters, you can divide by 10 because there are 10 millimeters in a centimeter. So, the diameter of the circle would be 4.4 centimeters. Happy calculating!
What is the area of a circle if the radius is 7 mm?
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).
What is the area of a circle with the radius of 9 millimeters?
Using 3.14 as Pi the area of circle is: 254.34
What is the circumference of a circle if the diameter is 6 feet?
Well, darling, if the diameter of a circle is 6 feet, then the radius is half of that, which is 3 feet. The formula for the circumference of a circle is 2πr, so plug in the radius (3 feet) and you get a sassy circumference of 6π feet. Hope that clears things up for you, sugar!
What is the circumference and area of a circle if the radius is 9.6 millimeters?
A circle with a radius of 9.6 millimeters has a circumference of 60.32 millimeters.
If the radius of the circle is 12 millimeters, then what is the diameter of this circle?
75.42
If the diameter of a circle is 40 millimeters what is the length of the radius?
20 millimeters
If the diameter of a circle is 14mm what is the radius?
The radius would be 7 millimeters.
What is the radius of a circle with a diameter of 328 millimeters?
Radius = 1/2 of the diameter = 328/2 = 164 millimeters
What is the circumference of a circle with a radius of 175 millimeters?
The circumference of a circle with a radius of 175 millimeters is about 1,100 mm (C = r x 2 x Pi).
The circle has a radius of 30 millimeters. What is the diameter of a circle in centimeters?
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
If the radius circle is 10 millimeters what is the circle's diameter?
20 mm. The diameter is always twice the radius.
What is the circumference of a circle that the radius of fifty millimeters?
Circumference is 314.159mm
What is the area of a circle with a radius of 15 millimeters?
711
What is the diameter of a circle with a radius of 150 millimeters?
300 mm
