Answer 2

Step-by-step explanation:

Let Radius Of circles touching externally be R1 & R2 then

Area Of Circle one A1 = π(R1)²

Area Of Circle two A2 = π(R2)²

Now, A1 + A2 = 52cm²

π{(R1)² + (R2)²} = 52cm²

and, R1 + R2 = 10 --- 1

squaring Above Equation Both Side,

(R1)² + (R2)² + 2(R1R2) = 100

But (R1)² + (R2)² = 52/π

52/π + 2(R1R2) = 100

2(R1R2) = 100-52/π

R1R2 = 50-26)/π ---- 2
