Answer:
The radius is 1/2 of the diameter. We know the diameter is a straight line that passes through the circle's center. A radius is a line segment is a part of a line that connects the center of a circle to the circle's perimeter.
D (diameter) = 2R (Radius)
Multiply the radius by 2 and you have the diameter!
Thus, to find the radius, divide the diameter by 2.
R (radius) = 1/2D (diameter)
