. 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
R_1^2 + R_2^2 = R^2
R_1+R_2=R
R_1+R_2 < R
R_1^2 + R_2^2 < R
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
