The diameter of B is 3 times the diameter of A.
So the linear scale factor is 3.
The area scale factor is, the linear scale factor squared.
So Area scale factor is: 3² = 9
To get the area of Circle B, just multiply the area of Circle A by the area scale factor:
Area of Circle B = 500 × 9
= 4500 metres squared
