Answer:
r1² + r2² is r².
Among the given options option (b) r² is the correct answer.
Step-by-step explanation:
Given :
Sum of the Areas of two circles with Radius r1 and r2 = Area of circle with Radius r
πr1² + πr2² = πr²
π(r1² + r2²) = πr²
[On cancelling π]
(r1² + r2²) = r²
Hence, r1² + r2² is r².

r1=a and r2=b
πa²+πb²=πr²
a²+b²=r²
so ans is (b)
