Answer:

The area of Circle 1 is 9 times greater than the area of Circle 2.

Explanation:

Use this formula:

Area = π * radius².

Determine given variables and Numbers:

Circle 1 has a radius of 9 yd.

Circle 2 has a radius of 3 yd.

Input Given Variables and Numbers:

Area of Circle 1 = π * (9 yd)²

Area of Circle 2 = π * (3 yd)²

Divide Both Formulas:

(π * (3 yd)²) / (π * (9 yd)²)

Simplify The Expression

(π * 3²) / (π * 9²)

= 9 / 81

= 1 / 9.
