find of the An archery target has three regions formed by three concentric circles as shown in Fig 15.8. If the diameters of the concentric circles are in the ratio `1:2:3`. , then find the ratio of the areas of three regions Fig. 15.8

Explanation

To solve the problem of finding the ratio of the areas of the three regions formed by three concentric circles with diameters in the ratio of 1:2:3, we can follow these steps:

### Step 1: Define the diameters
Let the diameters of the three circles be:
- \( d_1 = \lambda \)
- \( d_2 = 2\lambda \)
- \( d_3 = 3\lambda \)
