Question

the ratio of diameter and radius of a circle is

Answer 1

Radius=r
diameter= r/2
let's take radius as 1.
ratio of diameter and radius = 1/2/1 = 2:1

Answer 2

The ratio of diameter and the radius of a circle is 2:1.

• The value of diameter is 2r and radius is r. So, the ratio of diameter and circle is 2r/r = 2:1.

• In geometry, the radius is defined as the part of a line that joins the center of a circle or globe in its circle or boundary. It is an integral part of circles and spheres often abbreviated as 'r'.
• Radius is defined as the part of a line that connects the center to the circle of a circle or globe.
• The length of the radius is always the same from the center to any point in a circular or circular circle. It is part of the maximum length. In a circle, width is a line that passes through the center and meets a circle in opposite directions. It is twice as long as the diameter of the circle. In other words, the width of the circle is the line that runs through the center and divides the circle into two equal parts
