Answer:
9π cm²
Step-by-step explanation:
The formula for the area of a circle with radius r is:
[tex]A = \pi r^2[/tex]
To calculate the area of a circle with a radius of 3 cm, substitute r = 3 cm into the formula:
[tex]A=\pi \cdot (3 \sf \;cm)^2[/tex]
[tex]A=\pi \cdot 3^2\cdot \sf \;cm^2[/tex]
[tex]A=9\pi \sf \;cm^2[/tex]
Therefore, the area of the circle is 9π cm².
