Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.

Pi= 3.1416 circle / 3.1416=diameter

No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.

For a given area a circle has least perimeter. eg Let area = 100 sq cms. For the square or rectangle the perimeter = 40 cms For the circle the radius is square root of 100/3.1416 = 5.64 and the circumference = 2 x radius x 3.1416 = 35.44 cms

perimeter_of_quarter_circle = 1/2πr + 2r For the arc bit of the perimeter: circumference of circle = 2 x π x radius quarter of this = 1/2 x π x radius The two straight sides are radii which need to be added on making: perimeter_of_quarter_circle = 1/2 x π x radius + 2 x 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

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.

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

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

62/2pi which is close to 10
