It probably means that you are to work out certain properties of a circle.
you do math
I guess you mean:"How do you find the radius if you are given the diameter?"You take the diameter and divide it by 2.
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
If it is just the radius, it is half of the diameter. If you are given the circumference, divide the given measure value by 3.14. Then, divide the result by 2 to get the radius! Have fun! If you need any help with other math formula's just post another answer. I'll write full, complete, and correct answers that I'm sure about. David (venom751998)
Twice the radius.
the radius is half the diameter
2 * pi * radius
Radius = Diameter/2.
The radius is half the diameter.
Double the radius
It refers to the radius of a circle which is half of its diameter.
radius is half of a circle. when u make a line from the middle of the circle to the edge would be the radius:]
