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 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.

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
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
