1. If the sum of the areas of two circles with radii \(R_1\) and \(R_2\) is equal to the area of a circle of radius \(R\), then

2. If the sum of the circumferences of two circles with radii \(R_1\) and \(R_2\) is equal to the circumference of a circle of radius \(R\), then

\(R_1+R_2<R\)
\(R_1+R_2=R\)
\(R_1+R_2>R\)
Nothing definite can be said about the relation among \(R_1\), \(R_2\) and \(R\)
