Question

the radius of a circle is 2 feet. what is the circles area? round your answer to the nearest hundredth. square feet

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

Step3: Calculate the area

$A = 4\pi\approx4\times3.14159 = 12.56636$.

Step4: Round the result

Rounding $12.56636$ to the nearest hundredth gives $12.57$.

Answer:

$12.57$ square feet
