Answer :

To find the diameter of Circle B, we can follow these steps:

1. Understand the problem:
- We are given that Circle A has a radius of 50 cm.
- Circle B is three times larger than Circle A in terms of the radius.

2. Calculate the radius of Circle B:
- Since Circle B is three times larger than Circle A, the radius of Circle B will be 3 times the radius of Circle A.
- Radius of Circle A = 50 cm
- Radius of Circle B = 3 Radius of Circle A
- Radius of Circle B = 3
50 cm = 150 cm

3. Calculate the diameter of Circle B:
- The diameter of a circle is twice the radius. So, we need to multiply the radius of Circle B by 2.
- Diameter = Radius 2
- Diameter of Circle B = 150 cm
2 = 300 cm

Therefore, the diameter of Circle B is 300 cm.
