What do you have to do to the diameter to get the radius formula?

1 answer:

6 0

If you have the diameter and you want to find the radius, just remember that the diameter is half of a circle (circumference) and the radius is a quarter of a circle, and it can also be found by dividing the diameter by 2, because the radius is half of a diameter.

I hope this clears your confusion!
