The diameter is equal to half of the radius. So take the value of the diameter and divide it by two and that is your radius.

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.
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
How you find the area of a circle in BASIC?
It is fairly easy if you know what radius, diameter, and pi are. Basically all you have to do is multiply the radius by itself and then multiply your answer by pi. πr squared. If all you have is the diameter, then divide the diameter by two and then do the formula.
Does a diameter go all the way across or halfway across a circle?
A diameter goes all the way across a circle through the center. A radius goes half way across, from the center to any point on the circle. So a circle's diameter is two times its radius.All the way through the centre of the circle but the radius only goes half way from the centre of the circle
How do you find the perimeter if the radius is 100 millimeters?
First of all, you have to promise us that you're talking about a circle.We're going to assume that, since you mentioned 'radius'.The perimeter of a circle ... usually called its 'circumference' ... is (pi) x (the circle's diameter).The circle's diameter is (2) x (its radius).Diameter = 200 millimetersCircumference = (pi) x (200) = 628.319 millimeters (rounded)
Find the radius of a circle which has a diameter of 3.6cm?
The radius of a circle is the distance from the center to an outside edge of the circle. The diameter is the distance all the way across the circle. Therefore, the radius is half the value of the diameter.
How do you find the diameter of the circle if you have the area and radius?
All you have to do is multiply the radius by 2.

Which is more diameter or radius?
The diameter. The diameter is all the way across the circle, the radius is half of the diameter
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
What is the space inside a circle?
Circumference is the outside of the circle and the inside is the are of the circle. And inside of the circle, there is diameter and radius. Radius is from the center point to the edge of the circle and diameter is all the way across.
Diameter vs radius?
diameter is length all the way across a circle radius is half of the diameter which is a dot in the center of the circle and it goes to all sides of the circle and it equals the same # throughout the 360 degrees
Is the ratio of the radius to the diameter of all circles?
The ratio of radius to diameter for any circle is 1/2

How do you find the diameter of a circle which would touch all three angles of an equalateral triangle?
Double its radius
Does a diameter go all the way across or halfway across a circle?
