Question

what is the area of this circle in square centimeters? 3 cm 9π 6π 9π 30π

Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius of the circle.

Step2: Identify radius value

The radius $r = 3$ cm as given in the problem.

Step3: Substitute radius into formula

Substitute $r = 3$ into $A=\pi r^{2}$, we get $A=\pi\times(3)^{2}=\pi\times9 = 9\pi$ square - centimeters.

Answer:

$9\pi$ square centimeters
