Question 1070232
Ohkay, so imagine a circle, where, P and Q are the end points of a diametre ( so it's in the middle) And if O is in the middle of P and Q(diameter) and finishes with S, that means O and S are the radius (which is just half of the diamtre) Meaning QP (diameter)=2OS(radius)

So:
Diametre= 2x radius
PQ=2OS
