Plz ! a circle has a radius of 6x9y5 cm.

To solve this exercise, you must follow the proccedure below:

 1. You have that:

 - The formula for calculate the area of the circle is: A=πr² ("r" is the radius of the circle).
 -The problem says that the circle has a radius of 6x^9y^5 (r=6x^9y^5)

 2. When you substitute r=6x^9y^5 into A=πr², you obtain:

 A=πr²
 A=π(6x^9y^5 cm)²

 3. By applying the exponents properties, you have:

 A=36πx^18y^10 cm²

 4. Therefore, the answer is the second option: 36πx^18y^10
