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
