What is diameter vs radius?
While the radius of a circle runs from its center to its edge, the diameter runs from edge to edge and cuts through the center. A circle’s diameter essentially splits the shape in half.
What is the radius if the diameter is 10 cm?
Diameter is the longest line that you can draw in a circle passing through the centre of the circle. Radius is the line joining the centre of the circle to any point on the circumference. Answer: the radius of 10 cm diameter circle is 5 cm.
