Answer:

254 cm^2.

Explain:

The area of a circle is given by pi r squared. Pi has a constant value of 3.14. And the radius of the circle is 9 cm. The area equals pi R² equals 3.14 × 9² CM squared. 3.14 × 81 = 2.54.34cm^2 equals 254cm^2.

Answer:

254.4 in²

Explanation:

Area of a circle is given by the formula:


\pi r^(2)

Our radius is 9 so we substitute this into the equation:

π(9)² = 81π

81π = 254.4 in²
