Question

what is the area of the circle in terms of π? 3 cm a 6π cm² b 12π cm² c 9π cm² d $\frac{9}{4}π$ cm²

Explanation:

Step1: Recall the area formula

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

Step2: Substitute the radius value

Given that $r = 3$ cm, substitute $r$ into the formula: $A=\pi\times(3)^{2}$.

Step3: Calculate the result

$(3)^{2}=9$, so $A = 9\pi$ $cm^{2}$.

Answer:

C. $9\pi$ $cm^{2}$
