Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
you double the radius to find the diameter.
You already know the radius.
squares do not have a radius
A kite does not have a radius.
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
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.
double the radius or multiply by 2 the radius
diameter = 2*radius
triangles don't have radius'
pie times radius squared
to find the radius you have to measer trow the circle then divid by 2
