Answer: To find the area of a circle, you can use the formula A = πr², where A represents the area and r represents the radius.

Given that the radius of the circle is 8 cm, we can substitute this value into the formula:

A = π(8 cm)²

To find the area to the nearest tenth, we need to round our answer.

Calculating the area using a calculator or the value of π as 3.14, we have:

A = 3.14(8 cm)²

A = 3.14(64 cm²)

A ≈ 200.96 cm²

Rounding to the nearest tenth, the area of the circle is approximately 201.0 cm².
