If the sum of the areas of two circles with radii R1 and R2 is equal to the area of a circle of radius R, then
R1 + R2 < R
R12 + R22 = R2
R1 + R2 = R
R12 + R22 < R2
If the sum of the areas of two circles with radii R1 and R2 is equal to the area of a circle of radius R then
(a) R1+R2=R
(b) R1+R2>R
(c) R21+R22<R2
(d) R21+R22=R2
