Question

How it is solved? Step wise

Answer 1

Answer:here is your answer

Step-by-step explanation:

Area of circle 1 = π(10)^2 = 314 cm^2

Area of circle 2 = π(24)^2 = 1809.56 cm^2

Sum of Area= 314+1809.56= 2123.56 cm^2

Area of circle 3 =π(R)^2 = 2123.56

R^2 = 2123.56/π = 675.94 cm^2

R = 25.99 cm = 26 cm

Answer 2

R1 = 10 cm

R2 = 24 cm

r = ?

ATQ

$\pi {r}^{2} = \pi {r1}^{2} + \pi {r2}^{2}$

${r}^{2} = {r1}^{2} + {r2 }^{2} \\ r = \sqrt{100 + 576 } \\ r = \sqrt{676} \\ r = 24(aprox..)$
