Answer:

diameter=twice of radius or d=2r

and radius is half the diameter or r=d/2.

Step-by-step explanation:

As you know circle is a figure whose all points are equidistant from a fixed point or center point. the distant b/w center point and any point on the circle is called radius. and the line which passes through the center of circle and touches far both of center is called diameter.

mathematically you can understand in this way

diameter=twice of radius or d=2r

and radius is half the diameter or r=d/2.

Answer:

r = d/2

d = 2r

Step-by-step explanation:

The relationship between the radius and diameter of a circle can be explained by the formula

Radius r = diameter d /2

That’s the radius is equal to half of the diameter .

You can solve for the radius of a circle whenever the diameter of the circle is given by dividing the diameter by 2.

Also, since radius is equal to the half of a diameter,

r = d/2 , diameter can be solved by multiplying the radius by 2.

That’s diameter = 2r

Where r = radius of the circle
