Question

what is the area of the circle? 12 m a 144π m² b 24π m² c 36π m² d 12π m²

Explanation:

Step1: Recall area formula

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

Step2: Substitute radius value

Given $r = 12$ m, substitute into the formula: $A=\pi\times(12)^{2}$.

Step3: Calculate result

$(12)^{2}=144$, so $A = 144\pi$ m².

Answer:

A. $144\pi$ m²
