Question

please anybody solve this question !​

Answer 1

Step-by-step explanation:

PQ = 2

This means that radius of smallest circle = 1

Area of smallest circle = $\pi r^2 = \pi(1)^{2} = \pi = \frac{22}{7} = 3.14$

Now let the length of QR = x

Diameter of the largest circle = x + 2 + 1

Radius = $\frac{x+3}{2}$

Area of Largest circle = $\pi(\frac{x+3}{2})^{2}$

Diameter of medium circle = 2 + x

Radius of medium circle = $\frac{x+2}{2}$

Area of Medium Circle = $\pi(\frac{x+2}{2})^{2}$

Now It is given that area of medium circle is average of area of two other circle. Thus:
