4 units The radius of a circle is the distance from the center to the edge. The diameter of a circle is the distance from the edge, going through the center, to the opposite edge.
They both describe a circle. The radius is the length from the middle of the circle to the edge. The diameter is the length of a straight line going through the middle of the circle edge to edge.
diameter.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
The radius is the distance from the edge to the center. Diameter is distance from one edge through the center to the other edge. The diameter is twice the radius. If the radius is 1, then twice that is 2.

4 units The radius of a circle is the distance from the center to the edge. The diameter of a circle is the distance from the edge, going through the center, to the opposite edge.
The diameter is a straight line measured from the edge of the circle to the opposite edge passing through the center point
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
20 feet (just double it!) The radius is from the centre of the circle to the edge and the diameter is from the edge to the opposite edge! :)
A radius of a circle is from the center to the edge. A diameter goes from edge to edge across the center, so the diameter is twice the radius. 8.5 feet. ■

diameter.
A diameter of 84cm, means the circle is 84cm wide. A diameter is a line or measurement from one edge, through the centre, to the opposite edge of the circle.
A 6 inch circle is the measurement from one edge through the centre to the opposite edge. This line is known as the circle's diameter.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
Diameter is a straight line from edge to edge across the center. Perimeter or circumference is the distance around the circle.
