If the diameter of a circle is 5 in., what is the radius?
What is the relationship of the diameter of a circle to radius?
The diameter is the distance across the circle and the radius is the distance from the center of the circle to the edge of the circle.
I will be happy to check your answer.
2.5?
Right. The radius is 2.5
So you can see that the diameter is double the radius.
or you can say the radius is 1/2 the diameter.
The radius of a circle is like that friend who always accompanies the diameter. They are best buddies! In fact, the relationship between the diameter and the radius is pretty straightforward. If the diameter of a circle is 5 inches, then the radius would be half of that, so it would be 2.5 inches. Keep in mind that the radius never likes to miss out on the fun, so it's always half the size of the diameter. They're quite the dynamic duo, if you ask me!
To find the radius of a circle when given the diameter, simply divide the diameter by 2. In this case, the diameter is given as 5 inches, so dividing it by 2 gives us a radius of 2.5 inches.
The relationship between the diameter and radius of a circle is that the diameter is always twice the length of the radius. In other words, if you know the radius, you can find the diameter by multiplying the radius by 2. Conversely, if you know the diameter, you can find the radius by dividing the diameter by 2. This relationship holds true for all circles.
