A radius is a straight line from the circumference (boundary) of a circle to the centre. A diameter is a straight line that goes from the circumference to the centre and then continues until it reaches the circumference of the other side. In a circle, all points on the circumference are the same distance from the centre. As a result, the second part of the diameter is the same as the first. In other words, diameter = radius + radius = 2*radius.

Which is longer radius diameter?
diameter is longer. radius is half of diameter
How do you find the radius if the diameter is given?
the radius is half the diameter
If the diameter of a circle is 36 what is the radius?
The radius of a circle is always half of the diameter. Therefore, if the diameter of a circle is 36 units, the radius would be half of 36, which is 18 units. The formula for finding the radius from the diameter is radius = diameter / 2. So, in this case, the radius would be 18 units.
What is the radius of a circle if its diameter is cm?

What is half of a diameter of a circle?
