2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
The radius of a circle is a line that starts at the center of the circle and ends somewhere along the perimeter of the circle. The diameter is a line that starts at the perimeter of a circle, goes through the center of the circle, and ends at the opposite perimeter of the circle. This a diameter is twice as long as a radius and can be thought or as consisting of two radii.
No because the perimeter of a circle is its circumference
perimeter = pi * diameter, or 2 * pi * radius
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
No.
The circumference of a circle with a radius of 5cm is: 31.42 cm
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.

The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
The perimeter which is the circumference of a circle is: pi*diameter or 2*pi*radius
No because the perimeter of a circle is its circumference
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
perimeter = pi * diameter, or 2 * pi * radius
Radius = 40/2pi cm
you can divide the perimeter(circumference) by pi(3.14) and then once you get your answer you divide that by two giving you the length of the radius of the circle. ex: perimeter = 34pi 34pi/pi 34/2=diameter 16=radius
