The diameter.
The radius is the distance from the centre point to the edge.
Radius is half of the diameter - i.e. it is the distance from the centre to the edge of the circle.
The radius is from the centre to the rim of a circle.
The radius would be HALF the diameter, making the answer 1.5cm ! The diameter of a circle is the distance across it, passing through the centre. The radius is the distance from the centre to the edge.
It's longer than both. The circumference - is the distance around the circle... The diameter - is the distance across the circle, passing through the centre... The radius - is the distance from the centre of the circle to the edge.
The width of a circle is called the diameter. The distance from the centre to the edge is called the radius and the distance around the rim is called the circumference
The radius is the distance from the centre of the circle to the edge, the radius is half of the diameter. I hope this helps
... twice that. The radius is the distance from the centre to the edge, in a straight line. The diameter is that line continued from the centre to the edge, in the opposite direction. So a radius of 2 inches means a diameter of 4 inches.
From the centre of a circle to the outside edge is known as the radius.
Radius is always one-half of the diameter.This is because the radius is the distance from the edge of a circle to its centre, whereas the diameter is the distance from one edge of a circle to the other, through the centre - thus, effectively, twice the radius.Thus, if the radius of the circle is 10, then the diameter must be 2(10), or 20.
No.Circumference is the total distance around a plane figure. Usually a circle or ellipse.Diameter is the distance of a straight line from edge to edge passing through the centre of a circle.
