Final answer:

The area of a circle with a radius of 8 cm is calculated using the formula A = πr². Upon completing the calculation and rounding to two decimal places, the area is 201.06 cm², which corresponds to option b).

Step-by-step explanation:

To calculate the area of a circle, we use the formula A = πr², where π (pi) is approximately 3.1415927 and r is the radius of the circle. Given that the radius is 8 cm, we plug this value into the formula:

A = π(8 cm)²

A = 3.1415927 × (64 cm²)

A = 201.0619296 cm²

When rounding to two decimal places, the area is approximately:

A = 201.06 cm²

Therefore, the correct answer from the provided options is b) 201.06 cm².
