Question

the radius of a circle is 2 meters. what is the area? give the exact answer in simplest form. square meters

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

Step3: Calculate the result

$(2)^{2}=4$, so $A = 4\pi$ square - meters.

Answer:

$4\pi$
